Very simple
y = e^-x
the derivative of this would be...
y' = e^-x*ln(e) = e^-x
or
y' = -e^-x*ln(e) = -e^-x
basically, does this thing become negative?
calculus? gah!

it's actually not all that bad as people make it out to be, actually it's kinda fun :P
well id help but i only just passed it last year, and im doing statistics this year. however ill pass this question on to a friend that does calculus. ok?
never mind, hes excuse is he hasn't done derivatives yet. you have a 50/50 chance of being right though correct? take your chances?

well, i found out what it is, looks like i was forgetting my rules >_>
it's -e^-x
but thanks for helping out grey ghost! very much appreciated :P
but I'll be serious with you, derivatives only take about 20 minutes to learn and find; a bit longer than that to understand.
but essentially, if you can find a derivative; then you can probably solve any question without knowing how it works exactly.
I suck at limits though, the foundations of calculus persay ;_;
*-EsTi's brain explodes....@_@

help with what? i did nothing lol
and yea its not to hard to understand i remember doing em, but anything i have learnt last year i have already forgotten. Plus its Friday and im chilling out, no way am i in the mood to think :P
wow i love calculus, and i hate how they reverse the computation for differential calculus, lol
and yeah that's right, -e^(-x) is the answer
since someone want to have a simpler life, ive found out that there is differencial calculus calculator, lol, check it out

I can't get it to work, the applet doesn't start >_>.
Thanks for sharing though :D
