Let h(x)=tan2{2sin−1(cos(sin−13x))+2cos−1(sin(cos−13x))3}; whe – InterviewSolution

1.	Let h(x)=tan2{2sin−1(cos(sin−13x))+2cos−1(sin(cos−13x))3}; where x∈[−13,13], then the value of 10∑r=3h(1r2)=
Answer» Let $h (x) = {tan}^{2} {\frac{2 {sin}^{- 1} (cos ({sin}^{- 1} 3 x)) + 2 {cos}^{- 1} (sin ({cos}^{- 1} 3 x))}{3}};$ where $x \in [- \frac{1}{3}, \frac{1}{3}],$ then the value of $10 \sum r = 3 h (\frac{1}{r^{2}}) =$
