what is the derivative of 7arcsin(10x^2+15x-9)

Question

primeralph · Answer

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

anonymous · Answer

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.

lol he didn't give you the answer, he was giving you a way to solve the problem -_-

zepdrix · Answer

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

anonymous · Answer

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