∫Sin⁡−1x−Cos⁡−1xSin⁡−1x+Cos⁡−1xdx=\int \frac{\operatorname{Sin}^{-1} \sqrt{x}-\operatorname{Cos}^{-1} \sqrt{x}}{\operatorname{Sin}^{-1} \sqrt{x}+\operatorname{Cos}^{-1} \sqrt{x}} d x=
View answer and explanation
Correct option: A
4π[x−x22+xSin⁡−1x−12Sin⁡−11−x]−x+c\frac{4}{\pi}\left[\frac{\sqrt{x-x^2}}{2}+x \operatorname{Sin}^{-1} \sqrt{x}-\frac{1}{2} \operatorname{Sin}^{-1} \sqrt{1-x}\right]-x+c
The correct answer is A (4π[x−x22+xSin⁡−1x−12Sin⁡−11−x]−x+c\frac{4}{\pi}\left[\frac{\sqrt{x-x^2}}{2}+x \operatorname{Sin}^{-1} \sqrt{x}-\frac{1}{2} \operatorname{Sin}^{-1} \sqrt{1-x}\right]-x+c) because after simplifying the integral using trigonometric identities and integration by parts, the result matches option A.
