I need to find the derivative of
I knew to use the power rule, but I was coming up with
Is this the correct answer?
chain rule is present at any moment.
for example if you want to differentiate a simple function as then that is but that it's quite simple and then irrelevant to write, but having we can think this as the composition by letting and so by differentiating we get According to this we have that can be expressed as and then by differentiating we get (following up on what I said before)
