    differentiate the stuff inside the arcsin, then multiply that by 7/sqrt(1-(stuff inside arcsin)^2)

    Let \[y=7sin^{-1}(10x^2+15x-9)\] \[\frac{y}{7}=sin^{-1}(10x^2+15x-9)\]\[sin(\frac{y}{7})=(10x^2+15x-9)\]Differentiate both sides with respect to x.

    To start, do you know this derivative?\[\large y=\arcsin x \qquad \qquad y'=?\]

    differentiate the stuff inside the arcsin, then multiply that by 7/sqrt(1-(stuff inside arcsin)^2) i did this

    i know it's something like 1/sqrt(1-u)^2

    Yes that sounds right bee, \[\large y=\arcsin x \qquad \qquad y'=\frac{1}{\sqrt{1-x^2}}\]

    I looked at your post, 7/sqrt(1-(stuff inside arcsin)^2) But the only one I see is 7/1+(10x^2+15x-9)^2 since it's a plus there i know i'm doing something wrong

    oh so the final answer is 7x(20x+15)/sqrt(1-(10x^2+15x-9)^2
