I'm supposed to find the derivative of the following.
Using the form , or turning F(x) into F'(x) (Prime).
Anyway, I'm supposed to solve r=2/3 but I'm not sure how I'm supposed to turn this function into F'(x).
I think I'm supposed to do something like
But I'm not sure how I should be applying the exponent when r = 2/3 - or whether I'm on the right track in that case.
to get that section, then -1 from the exponent.
Thanks again, the Pi threw me off..
