Question

(sin^-1){(x^2)/[(sqrt(x^4)+(a^4))]}
differentiate w.r.t. x

Answer 1

we can substitute \[x ^{2} = a ^{2}\sin \theta\]

Answer 2

\[\sin^{-1}\left( \frac{x^{2}}{\sqrt{x^{4}+a^{4}}} \right)\]?

Answer 3

its a^4 not a^2 :D

Answer 4

yea thts it

Answer 5

so,
let x^2 = a^2 sinM
then
2xdx = a^2cosM.dM

Use this substituion. you 'll land up with:
