I am to find the derivative of f(x) and g(x):
So far, I know the following:
- The derivative of tan(x) = sec(x)^2
- The derivative of sec(x) = sec(x)tan(x)
So, I have tried the following steps to get the derivative of f(x):
1) Convert to sec(x) using the chain rule --> (sec(x^4)*4x^3)^2
2) This equals ((4x^3)(sec(x^4))^2
For g(x), however, I am not quite sure where to begin.
As well, I do not believe that ((4x^3)(sec(x^4))^2 = f'(x).
Can anyone please show me where I went wrong trying to find the derivative of f(x), as well as point me in the right direction in finding g(x)?
