heh he's just asking for verification. id ont see what's the problem

What if he's an aerospace engineer and I get on a plane he'll design in the future?
I shudder at the prospect.

Well then he can take out his trusty ti-89 and have it do it for him

then i would be praised for making sure my calculations are correct instead of assuming i can't go wrong or just hoping for the best.

No need to turn this thread into your personal brawl. The man got what he wanted to know.

why is e^(-x-y-z) does that mean to the power of a bunch of different variables? Are you taking the derivative or the antiderivative... whats a partial derivative?

First time posting a link, hope this works right. ;)

Hope you don't use this site to find your answers but rather check your answers

yeah. taking the detivieative. paritlalll directifative with respect to x maenas treaintg the other variables lsike cosntnatns

Are you on something or drunk... or just typed it wrong? So yes taking derivitive, partial directifative?

sorry i meant yes that is taking derivative, but it's a particial differentiation, all that means is you take the derivative with respect to 1 variable and treat the other variables in the equation as constants

is the partial derivative with respect to x

-2e^(-x-y-z) ?

when doing partial derviatives just pretend all the other variables are constants. So in this case x and z would be constants...good job on getting the right answer! :)
