A) \[\frac{\pi x}{2}\]
B) \[\frac{\pi {{x}^{2}}}{2}\]
C) \[\frac{\pi x-{{x}^{2}}}{2}\]
D) \[\frac{\pi x+{{x}^{2}}}{2}\]
Correct Answer: C
Solution :
\[\int_{{}}^{{}}{{{\sin }^{-1}}(\cos x)\,dx}=\int_{{}}^{{}}{\left\{ \frac{\pi }{2}-{{\cos }^{-1}}(\cos x) \right\}}\,dx\] \[=\frac{\pi }{2}x-\frac{{{x}^{2}}}{2}=\frac{\pi x-{{x}^{2}}}{2}\].You need to login to perform this action.
