Question

Transcribed Image Text:Find the derivative of the function.
Step 1
We recall that the derivative of the function y = sin¯¹(x) is given by the following.
f(x) = sin ¹(7x)
√1-x²
We note that for the given function, f(x) = sin¯¹(7x), we will need to combine the formula above with the chain rule as follows, where u = 7x.
du

V1-u² dx
U = 7x

So, our first step is to determine
