ohhh man I screwed up royally on both derivatives........didn't notice that you have to use the product rule first

first derivative:

sorta like ... ur 'steps'

I don't understand shit!!....:P so I'm officialy hi-jacking the thread:d

[Sweeney921]

1. you have to use the product rule to derive it because there's 2 different variables multiplied by one another (x and e)
2. Product rule: (derivative of first variable multiplied by the original second variable)+(derivative of second variable multiplied by the original first variable)

From there on it's all algebra, but some pretty complicated stuff. I'm not gonna attempt the second derivative, I know I'll mess it up somewhere.

ah i hate all the different rules. i can never keep them straight. def my worst part of math.

ehhh **** this shit

Lol, I'll help

my solution, use produt rule; uv'+vu'

[man 430gt]

my solution, use produt rule; uv'+vu'

Math genuis?

[Bob]

and the second its all done with the power rule, derivative of e^u rule, and product rule. Quite simple really, but a pain in the ass to make sure everything's kept straight. I haven't checked this, no guarantees.

my solution, use produt rule; uv'+vu'

looking at that, i might not have done the derivative of e^u correctly. but i think i did. one of us is wrong.

Yeah I was gonna point that out but my dog was biting my leg so I was kinda of busy ( ).

hope this is clearer

hope this is clearer

That just hurts...
