# Som differenntiation from interesting p3 watch

1. Just checking....[arent yall excited about p3 tomorrow lol]

e^2x^2+4x=y

dy/dx=[4x+4]e^2x^2+4x right?

no, ive just soiled myself after being reminded
3. OK. Anything of the form e^f(x) has derivative f'(x)*e^f(x). In your case, f(x) = 2x^2 + 4x and so f'(x) = 4x + 4.

A simple yes or no would have been FINE.

depends on whether this is meant to be:

y = 4x + e^2(x^2)

or y = e^(2(x^2)+4x), which I think is how Jonny interpreted it.
