Question

${\sin }^{-1}\left(\frac{9}{8}\right)$ is equal to

• A. ${\cos }^{-1}\left(\frac{x-4}{5}\right)+C$
• B. $si{n}^{-1}\left(\frac{x-4}{5}\right)+C$
• C. $si{n}^{-1}\left(\frac{5}{x-4}\right)+C$
• D. None of these

Answer 1

Answer: (B)

Let $l={\int }_{}^{}\frac{1}{\sqrt{9+8x-x^2}}dx$ $\frac{4W}{3}$ $\frac{5W}{2}$ $\frac{\pi }{2}$
