00:00:05,887 --> 00:00:06,393

4
00:00:06,338 --> 00:00:06,633

5
00:00:06,658 --> 00:00:07,129

6
00:00:07,298 --> 00:00:09,021

7
00:00:08,967 --> 00:00:09,366

8
00:00:09,480 --> 00:00:09,922

9
00:00:10,959 --> 00:00:11,660

10
00:00:11,979 --> 00:00:12,559

11
00:00:12,487 --> 00:00:12,905

12
00:00:13,838 --> 00:00:19,093
สวัสสวัสดีนะคะสวัสดีวันศุกร์นะคะลูกๆทุกคนนะคะ

13
00:00:19,599 --> 00:00:22,234
วันนี้เจอกับคุณเจนอีกแล้วนะคะ

14
00:00:22,548 --> 00:00:26,287
2 ชั่วโมงแรกของวันนี้วันนี้เป็นไงบ้างคะลูกอากาศดีไหม

15
00:00:26,517 --> 00:00:27,010

16
00:00:26,967 --> 00:00:27,486

17
00:00:27,417 --> 00:00:28,486
หนาว

18
00:00:28,567 --> 00:00:29,761
อากาศดีเนาะ

19
00:00:29,780 --> 00:00:31,500
ตื่นมาอากาศสดใสเลย

20
00:00:31,893 --> 00:00:32,387

21
00:00:32,399 --> 00:00:34,056
อากาศเย็นสบาย

22
00:00:34,593 --> 00:00:35,205

23
00:00:35,548 --> 00:00:36,892
แต่สักพักนะ

24
00:00:37,272 --> 00:00:40,034
สักพักนึงอีกสักชั่วโมงสองชั่วโมงเดี๋ยวก็ร้อน

25
00:00:40,150 --> 00:00:43,737
แหวนช่วงนี้อากาศค่อนข้างเปลี่ยนแปลงบ่อยนะคะ

26
00:00:43,621 --> 00:00:47,913
ลูกๆก็ต้องดูแลตัวเองรักษาสุขภาพตัวเอง

27
00:00:48,289 --> 00:00:49,243

28
00:00:49,451 --> 00:00:53,820
หนาวก็รีบอาบน้ำให้ไวไม่อาบแช่

29
00:00:53,738 --> 00:00:54,426

30
00:00:54,440 --> 00:00:54,889

31
00:00:54,631 --> 00:00:55,702
จะได้ไม่

32
00:00:55,722 --> 00:00:57,569
ไม่สบาย

33
00:00:57,519 --> 00:00:57,984

34
00:00:57,968 --> 00:00:58,985
นะคะ

35
00:00:58,930 --> 00:01:01,286
โอเควันนี้นะคะ

36
00:01:01,230 --> 00:01:03,166
คุณจะมาทบทวน

37
00:01:03,790 --> 00:01:05,576
ในเรื่องของอนุกรม

38
00:01:05,981 --> 00:01:08,264
ในชั่วโมงที่แล้วที่เรา

39
00:01:08,348 --> 00:01:11,877
เรียนกับครูเจนไปเรื่องของอนุกรมความหมายของอนุกรมใช่ไหมคะ

40
00:01:11,798 --> 00:01:13,261
วันนี้

41
00:01:13,340 --> 00:01:14,450
น่าจะมา

42
00:01:14,500 --> 00:01:14,987

43
00:01:14,690 --> 00:01:17,711
ทบทวนอีกครั้งนึงนะคะเพราะว่า

44
00:01:17,761 --> 00:01:18,051

45
00:01:18,148 --> 00:01:20,450
ในเรื่องของการหาผลบวกลำดับ

46
00:01:20,580 --> 00:01:21,866
อนุกรม

47
00:01:21,873 --> 00:01:23,191
มันมีหลายวิธี

48
00:01:24,491 --> 00:01:26,554
ชั่วโมงที่แล้วเรียนแค่วิธีเดียว

49
00:01:26,790 --> 00:01:28,051
เนาะ

50
00:01:28,327 --> 00:01:30,453
วันอื่นนะคะรบกวนนิดนึง

51
00:01:30,508 --> 00:01:30,933

52
00:01:31,221 --> 00:01:33,571
จำได้ไหมคะอนุกรมหมายถึงอะไรคะ

53
00:01:33,649 --> 00:01:33,888

54
00:01:33,839 --> 00:01:36,841
อนุกรมคืออะไรใครตอบได้บ้าง

55
00:01:37,039 --> 00:01:37,556

56
00:01:38,651 --> 00:01:40,355
อนุกรมคืออะไรคะลูก

57
00:01:40,829 --> 00:01:41,630

58
00:01:41,720 --> 00:01:42,178

59
00:01:42,359 --> 00:01:42,558

60
00:01:42,619 --> 00:01:43,178

61
00:01:43,188 --> 00:01:44,465
อนุกรมคือ

62
00:01:44,472 --> 00:01:45,486
ได้ไหม

63
00:01:45,950 --> 00:01:47,420
ชื่ออะไรเอ่ย

64
00:01:47,680 --> 00:01:48,067

65
00:01:47,937 --> 00:01:49,676
ใครอยากตอบบ้างคะ

66
00:01:49,729 --> 00:01:50,680

67
00:01:52,348 --> 00:01:52,778

68
00:01:52,868 --> 00:01:55,798
จำได้ไหมจำไม่ได้อ่านทบทวนนะ

69
00:01:55,692 --> 00:02:00,571
อนุกรมคืออะไรคะอนุกรมคือผลบวกของลำดับ

70
00:02:00,617 --> 00:02:00,899

71
00:02:00,748 --> 00:02:01,021

72
00:02:00,998 --> 00:02:01,453

73
00:02:01,510 --> 00:02:01,985

74
00:02:01,898 --> 00:02:02,107

75
00:02:02,147 --> 00:02:02,604

76
00:02:02,280 --> 00:02:02,721

77
00:02:02,668 --> 00:02:02,880

78
00:02:02,797 --> 00:02:03,014

79
00:02:02,927 --> 00:02:04,328
โอเคไหม

80
00:02:04,720 --> 00:02:05,290

81
00:02:05,360 --> 00:02:09,473
เคนะอนุกรมนะคะคือผลบวกของลำดับ

82
00:02:10,227 --> 00:02:12,993
กูจะทบทวนนะตัวอย่างเช่น

83
00:02:13,428 --> 00:02:15,671
ถ้าเขาให้ลำดับมา

84
00:02:15,608 --> 00:02:17,902
135

85
00:02:17,849 --> 00:02:18,349

86
00:02:18,299 --> 00:02:18,939

87
00:02:19,199 --> 00:02:19,700

88
00:02:19,708 --> 00:02:21,498

89
00:02:21,440 --> 00:02:21,695

90
00:02:21,700 --> 00:02:24,571
อนุกรมของลำดับนี้คืออะไรคะ

91
00:02:25,670 --> 00:02:28,753
อนุกรมของระดับนี้ก็คือ

92
00:02:28,938 --> 00:02:31,232
ลำดับแต่ละลำดับใช่ไหมคะ

93
00:02:31,557 --> 00:02:32,534
นำพด

94
00:02:32,707 --> 00:02:36,989
ที่ 1 2 3 4 5 ในลำดับเนี่ยมาบวกกันให้หมดเลย

95
00:02:37,780 --> 00:02:38,128

96
00:02:38,160 --> 00:02:39,060
แค่นั้น

97
00:02:38,987 --> 00:02:42,378
อนุกรมของลําดับ 1 3 5 7 9

98
00:02:42,960 --> 00:02:45,456
ก็คือ 1 + 3

99
00:02:45,979 --> 00:02:46,994
+ 5

100
00:02:47,318 --> 00:02:48,255
+7

101
00:02:48,350 --> 00:02:49,435
+ 9

102
00:02:49,692 --> 00:02:53,285
แล้วเราก็หาผลลัพธ์ออกมาซึ่งมีค่าเท่ากับเท่าไหร่คะ

103
00:02:53,348 --> 00:02:54,001

104
00:02:53,987 --> 00:02:55,442
25 นั่นเอง

105
00:02:55,967 --> 00:02:56,542

106
00:02:56,796 --> 00:02:57,174

107
00:02:57,059 --> 00:02:59,241
โอเคไหมคะอันนี้เข้าใจไหมลูก

108
00:02:59,427 --> 00:03:01,266
เข้าใจนะ

109
00:03:01,291 --> 00:03:03,820
ชายอนุกรมคือผลบวกของลำดับ

110
00:03:04,038 --> 00:03:04,735

111
00:03:04,939 --> 00:03:06,947
ถ้ากำหนดให้

112
00:03:06,989 --> 00:03:07,802

113
00:03:08,138 --> 00:03:09,547
หนูดูนะลูก

114
00:03:09,807 --> 00:03:12,962
มีตัวแปรใหม่ขึ้นมานะคะตอนนี้ต้องจำนะ

115
00:03:13,457 --> 00:03:14,143

116
00:03:14,157 --> 00:03:16,276
ถ้ากําหนดให้ sn

117
00:03:17,238 --> 00:03:21,205
แทนผลบวก n พจน์แรกของลำดับ a n

118
00:03:22,486 --> 00:03:22,922

119
00:03:23,449 --> 00:03:23,832

120
00:03:23,830 --> 00:03:31,003
ดูนะคะถ้ากำหนดให้ sn เป็นผลบวก n พจน์แรกของลำดับ

121
00:03:31,067 --> 00:03:31,761

122
00:03:32,608 --> 00:03:32,923

123
00:03:32,867 --> 00:03:35,037
เราจะได้ sn

124
00:03:35,111 --> 00:03:36,057
เอากลับ

125
00:03:36,457 --> 00:03:37,654

126
00:03:37,666 --> 00:03:42,861
+ A2 + A3 + ไปเรื่อยๆจนถึง

127
00:03:42,927 --> 00:03:43,868

128
00:03:44,466 --> 00:03:44,831

129
00:03:45,617 --> 00:03:48,876
อันนี้คืออยู่ในรูปของอนุกรมแล้วนะคะ

130
00:03:48,821 --> 00:03:49,100

131
00:03:49,067 --> 00:03:49,339

132
00:03:49,469 --> 00:03:54,924
fn ตรงนี้แทนผลบวกของลําดับและอนุกรมนั้นเอง

133
00:03:54,775 --> 00:03:55,774

134
00:03:55,988 --> 00:03:56,492

135
00:03:56,438 --> 00:03:57,059

136
00:03:57,599 --> 00:04:00,232
มาดูต่อไปนะคะลูก

137
00:04:00,987 --> 00:04:01,266

138
00:04:01,189 --> 00:04:01,446

139
00:04:01,376 --> 00:04:01,929

140
00:04:02,468 --> 00:04:04,050

141
00:04:04,070 --> 00:04:05,334

142
00:04:05,350 --> 00:04:05,632

143
00:04:05,537 --> 00:04:09,438
เราจำได้ใช่ไหมเรื่องของลำดับจำกัด

144
00:04:09,955 --> 00:04:10,252

145
00:04:10,148 --> 00:04:12,584
ลำดับจำกัดจำได้ใช่ไหมคะ

146
00:04:12,705 --> 00:04:12,976

147
00:04:14,001 --> 00:04:18,601
ลำดับที่มี A1 A2 A3 ไปเรื่อยๆจนถึง n

148
00:04:19,887 --> 00:04:21,548
แบบนี้เรา

149
00:04:21,617 --> 00:04:22,950
บอกได้ว่า

150
00:04:24,246 --> 00:04:26,691
มีกี่พจน์ในลำดับนี้ถูกไหมคะ

151
00:04:26,615 --> 00:04:27,883
bnk

152
00:04:28,149 --> 00:04:28,437

153
00:04:28,665 --> 00:04:33,037
ถ้าเราเขียนในรูปของอนุกรมมันจะเป็นอนุกรมจำกัด

154
00:04:33,408 --> 00:04:33,788

155
00:04:33,989 --> 00:04:35,386
ก็คือ A1

156
00:04:35,389 --> 00:04:39,346
+ A2 + A3 ไปเรื่อยๆจนถึง + a n

157
00:04:41,345 --> 00:04:42,496
นะคะ

158
00:04:42,568 --> 00:04:45,248
ถ้าเป็นลำดับอนันต์ล่ะ

159
00:04:45,448 --> 00:04:48,298
อันดับอนันต์ก็คืออันดับที่เรา

160
00:04:48,400 --> 00:04:48,672

161
00:04:49,038 --> 00:04:50,894
ไม่สามารถบอกได้ว่ามีกี่พจน์

162
00:04:51,086 --> 00:04:51,846

163
00:04:51,987 --> 00:04:52,232

164
00:04:53,593 --> 00:04:56,974
vn1 A2 A3 ไปเล่นถึง n

165
00:04:56,854 --> 00:04:58,894
แล้วยังมีต่อไปเรื่อยๆอีก

166
00:04:58,904 --> 00:04:59,201

167
00:04:59,869 --> 00:05:04,734
คือเราไม่รู้ว่ามีกี่โพสต์บอกไม่ได้ถ้ามาเขียนในรูปอนุกรม

168
00:05:04,865 --> 00:05:06,514
ก็จะเป็นอนุกรมอนันต์

169
00:05:07,356 --> 00:05:12,141
นะคะก็คือ A1 + A2 + A3 + ไปเรื่อยถึง n

170
00:05:12,035 --> 00:05:14,489
แล้วยังบวกต่ออีกไปเรื่อยๆ

171
00:05:16,196 --> 00:05:19,491
แบบนี้เวลานั้นตรงนี้เราสามารถสรุปได้ว่า

172
00:05:19,726 --> 00:05:22,222
อนุกรมจำกัด

173
00:05:22,158 --> 00:05:25,151
ก็คือมาจากลำดับจำกัดนั่นเอง

174
00:05:26,128 --> 00:05:29,216
นานและอนุกรมอนันต์ก็คือมาจาก

175
00:05:29,144 --> 00:05:30,480
น้ำหนักขนาดนั้นเอง

176
00:05:30,544 --> 00:05:32,199
นะคะ

177
00:05:32,467 --> 00:05:33,052

178
00:05:32,987 --> 00:05:34,836
ทีนี้มาดูตัวแปร

179
00:05:35,096 --> 00:05:37,208
ในแต่ละตัวใน

180
00:05:37,148 --> 00:05:38,606
อนุกรมนี้นะคะ

181
00:05:38,687 --> 00:05:38,956

182
00:05:39,198 --> 00:05:40,473
ตัวแรกคือ

183
00:05:40,548 --> 00:05:40,788

184
00:05:40,868 --> 00:05:41,718

185
00:05:41,825 --> 00:05:44,313
A2 A3 A4 ตรงนี้

186
00:05:44,326 --> 00:05:47,209
ลูกๆน่าจะพอจำได้ว่ามันคือ

187
00:05:47,468 --> 00:05:49,999
A1 ก็คือกดที่

188
00:05:50,785 --> 00:05:51,815
พจน์ที่

189
00:05:52,335 --> 00:05:56,170
หนึ่งในโลกก็คือพจน์ที่

190
00:05:57,328 --> 00:05:58,659
2 ใช่ไหม

191
00:05:58,665 --> 00:06:00,591
A3 ก็คือพจน์ที่

192
00:06:00,535 --> 00:06:00,816

193
00:06:00,857 --> 00:06:01,999
3

194
00:06:02,007 --> 00:06:03,981
a n ก็คือพจน์ที่

195
00:06:04,307 --> 00:06:05,276

196
00:06:05,465 --> 00:06:05,693

197
00:06:05,716 --> 00:06:06,152

198
00:06:06,678 --> 00:06:11,387
ซึ่งตัวแปรในตรงนี้ที่เราต้องลุกต้องเข้าใจและต้องจำให้ได้ตรงนี้นะลูก

199
00:06:11,106 --> 00:06:12,196
sn

200
00:06:12,706 --> 00:06:13,250

201
00:06:13,216 --> 00:06:16,730
วันนี้ขึ้นมาใหม่นะแกมาใหม่นะลูก sn

202
00:06:16,666 --> 00:06:21,184
คือผลบวก n พจน์แรกของลำดับ a n นั่นเองหรือ

203
00:06:21,286 --> 00:06:22,620
อนุกรมนั้นเอง

204
00:06:23,467 --> 00:06:27,773
มีไหมทีนี้มาดูการหาอนุกรมนะคะ

205
00:06:28,204 --> 00:06:28,452

206
00:06:28,904 --> 00:06:29,439

01:25:22,621 --> 01:25:22,861

1491
01:25:23,014 --> 01:25:23,400

1492
01:25:24,091 --> 01:25:24,558

1493
01:25:28,334 --> 01:25:34,535
โอเคนะคะวันนี้นะคะลูกๆ 5/1

1494
01:25:35,251 --> 01:25:38,868
อย่าทำเก่งมากนะส่วนใหญ่คือวิธีทำเข้าใจ

1495
01:25:38,700 --> 01:25:39,208

1496
01:25:39,280 --> 01:25:43,710
เข้าใจว่าการหาอนุกรมก็คือการหาผลบวกของ

1497
01:25:43,642 --> 01:25:43,922

1498
01:25:43,893 --> 01:25:44,470

1499
01:25:44,479 --> 01:25:44,746

1500
01:25:44,850 --> 01:25:45,165

1501
01:25:45,111 --> 01:25:48,555
ก่อนอื่นเราต้องหาลำดับแต่ระดับให้ได้ก่อนถูกไหมคะ

1502
01:25:48,821 --> 01:25:49,530

1503
01:25:49,472 --> 01:25:52,734
a n แต่ละตัวออกมาให้ได้ก่อน

1504
01:25:52,731 --> 01:25:55,240
โจทย์ข้อนี้ 3 n + 1

1505
01:25:55,872 --> 01:25:56,140

1506
01:25:56,004 --> 01:26:00,376
เขาไปหา F5 ลูกๆเข้าใจค่ะว่าลูกๆต้องหา

1507
01:26:00,290 --> 01:26:01,110

1508
01:26:02,286 --> 01:26:06,703
ทั้ง 5 ก่อนคือ A1 A2 A3 A4 A5 ให้ได้ก่อน

1509
01:26:06,702 --> 01:26:08,295
จากนั้นค่อยนำ

1510
01:26:08,240 --> 01:26:08,506

1511
01:26:08,690 --> 01:26:12,658
A1 A2 A3 A4 A5 + กัน

1512
01:26:13,233 --> 01:26:15,211
แล้วเราถึงจะได้คำตอบ

1513
01:26:15,290 --> 01:26:17,715
ของการกดเงินออกมา

1514
01:26:18,101 --> 01:26:18,384

1515
01:26:18,419 --> 01:26:22,013
ณตอนนี้ลูกๆส่วนใหญ่คือเอาใจ

1516
01:26:21,942 --> 01:26:26,053
แต่ก็มีหลายคนนะคะที่ยังบวกเลขไม่ไม่ถูกไม่คล่อง

1517
01:26:25,979 --> 01:26:28,561
พรุ่งนี้คุณเจนฝากให้ไปฝึกนะคะ

1518
01:26:28,479 --> 01:26:28,789

1519
01:26:28,798 --> 01:26:30,124
ฝึกการบวกเลข

1520
01:26:30,079 --> 01:26:30,307

1521
01:26:30,341 --> 01:26:31,233
มาขึ้น

1522
01:26:31,300 --> 01:26:31,524

1523
01:26:31,623 --> 01:26:31,862

1524
01:26:32,011 --> 01:26:35,531
หรือบางคนที่ยังเขียนไม่ทัน

1525
01:26:36,423 --> 01:26:36,680

1526
01:26:36,679 --> 01:26:39,240
สายตาไม่ค่อยดีก็มานั่งใกล้ๆนะลูกนะ

1527
01:26:40,530 --> 01:26:43,191
บวกเลขไม่บวกเลขไม่คล่องให้ไปฝึก

1528
01:26:43,091 --> 01:26:43,297

1529
01:26:43,341 --> 01:26:46,501
ดูแม่สูตรคูณดูการบวกเลข

1530
01:26:46,540 --> 01:26:46,924

1531
01:26:46,808 --> 01:26:48,761
อันนี้เลขแค่หลักเดียวนะลูกนะ

1532
01:26:48,660 --> 01:26:48,953

1533
01:26:49,171 --> 01:26:49,420

1534
01:26:49,491 --> 01:26:49,789

1535
01:26:49,690 --> 01:26:50,251

1536
01:26:50,260 --> 01:26:53,808
เลขหลักเดียวเลข 2 หลักคือเราต้องไปซ้อมเยอะๆนะคะ

1537
01:26:53,721 --> 01:26:54,990

1538
01:26:55,332 --> 01:26:55,684

1539
01:26:56,221 --> 01:26:56,521

1540
01:26:56,610 --> 01:27:00,089
มาถึงตรงนี้มีใครสงสัยอยากจะถามอะไรคุณเจนไหมคะ

1541
01:27:00,320 --> 01:27:03,376
ยังมีข้อสงสัยอะไรไหมเกี่ยวการหาอนุกรมตรงนี้

1542
01:27:03,783 --> 01:27:07,641
ไม่มีเนาะเขาใจดีมากลูก

1543
01:27:07,620 --> 01:27:10,753
นี่ไม่เข้าใจมึงไม่ถามมึงไม่ทำ

1544
01:27:10,693 --> 01:27:13,136
ไม่ได้นะคะลูกนะ

1545
01:27:13,391 --> 01:27:16,866
เป็นนักเรียนหน้าที่เราเคยเรียนหนังสือนะลูกนะก็ต้องตั้งใจเรียน

1546
01:27:17,040 --> 01:27:18,621
วันนี้

1547
01:27:18,641 --> 01:27:22,749
วันนี้คุณเจนก็ฝากสำหรับเรื่องของการหาอนุกรมนะคะ

1548
01:27:22,932 --> 01:27:24,850
จากการรีเช็คแล้ว

1549
01:27:25,049 --> 01:27:25,932
