Hello,

I am doing a list of problems to do and have experienced some difficulty doing a particular one.

It asks to find the derivative of

f(x) = sin^2 (1+cos^3 (1+tan^4 (1+x))).

I've added a space ahead of exponents to avoid confusion, but it is all together.

Now, I don't know whether to use the chain rule multiple times, or how that would work, or anything. I don't know whether to see "(1+cos^3 (1+tan^4 (1+x)))" to sin^2 as you would see it as sin^2 x or something. I'm very confused.

Any help would be greatly appreciated, thank you!
