梯形法則及二項分佈

) ( 3 ( cos sin-1 K yx
1 Exp +/- 9 9 + ( sin
( K sin-1 1 ) ) x2 )
) + A nCr ( B + K
C yx 1 Exp +/- 9 9 )
× C yx ( B + K +
1 Exp +/- 9 9 ) ( 1
- C ) yx ( A - B
- K ) - K - 1 +
ANS + ( K + 1 STO F1 或 F2

如何在程式中加入K字元

 

例題1: 若X ~ Bin(9,0.5),求P(X=4)。

按 2ndF DEL (必要) RCL F1 ALGB 9 = 4 = 0.5 = (顯示答案為0.24609)

 

例題2: 若X ~ Bin(9,0.5),求P(4≦X≦6)。

按 2ndF DEL (必要) RCL F1 ALGB 9 = 4 = 0.5 = (顯示P(X=4)的值) = (顯示P(X=4)+P(X=5)的值)

= (顯示P(X=4)+P(X=5)+P(X=6)的值,答案為0.65625)

 

例題3: 梯形法則,子區間數目為10,計算

按 2ndF DEL (必要) 2ndF ex 2ndF ALPHA X (變數X的函數方程) RCL F1

∫dx 0 = 1 = 10 = (顯示1.719713491)

所以=1.719713491
