Quick question

[mdchesne]

studying for exam... got caught on the little technicalities from oldschool math...

is the derivative of e^5x
5e^5x... or just e^5x?

e^5X = e^5 . e^x = Constant * e^x
Derivative = e^5x

d/dx(e^f(x)) = f`(x)e^f(x)

i believe 5e^5x - don't hold me to that though as i haven't performed calculus in some time now...

i think whitecloak's right. insdie/outside derivative funtion. k, thanks guys

I think he is correct. Neglect my answer.

f'(5x) = 5 so should be 5e^5x (alright maybe my memory isn't so bad after all).
