A) \[\frac{1}{2}\]
B) \[1-\frac{1}{\sqrt{2}}\]
C) 1
D) None of these
Correct Answer: B
Solution :
[b] We have \[0<x<\pi /4\] \[0<x<0.8\] [x]=0 \[\int\limits_{0}^{\pi /4}{\left[ sinx.d(x- \right[x])}\] \[=\int\limits_{0}^{\pi /4}{sinx.d\left( x-0 \right)}\] \[=-(cosx)_{0}^{\pi /4}\] \[=1-\frac{1}{\sqrt{2}}\]You need to login to perform this action.
