A) \[2\sqrt{1-x}+c\]
B) \[-2\sqrt{1-x}+c\]
C) \[-{{\sin }^{-1}}\sqrt{x}+c\]
D) \[{{\sin }^{-1}}\sqrt{x}+c\]
Correct Answer: B
Solution :
We have, \[\int_{{}}^{{}}{\frac{dx}{\sqrt{1-x}}}\] or \[I=\int_{{}}^{{}}{{{(1-x)}^{-1/2}}dx}\] \[I=\frac{{{(1-x)}^{\frac{-1}{2}+1}}}{(-1)\,\left( -\frac{1}{2}+1 \right)}+c\] Þ \[I=-2\sqrt{1-x}+c\].You need to login to perform this action.
