If we assume this to be true, then: lim 1 h h e e h + - = definition of derivative Now we attempt to find a general formula for the derivative of using the definition. x y e = ( 29 lim x h x x h d e e e dx h + - = lim x h x h e e e h - = 1 lim h x h e e h - = 1 lim h x h e e h - = 1 x e = x e = This is the slope at x=0, which we have assumed to be 1. ( 29 x x d e e dx = x e is its own derivative! If we incorporate the chain rule: u u d du e e dx dx = We can now use this formula to find the derivative of x a ( 29 x d a dx ( 29 ln x a d e dx ( and are inverse functions.) x e ln x ( 29 ln x a d e dx ( 29 ln ln x a d e x a dx (chain rule) (...
