Math question
Er... verify something for me guys; Is the derivative ofequal toCode:sin(cos(x))Code:-cos(cos(x))sin(x)
That's not what I got - I got
sin(-sin(x)) * cos(cos(x))
I could be wrong, though.

Where did that extra sine come from?
Chain rule.

Code:f(x) = sin(cos(x))Right?Code:f'(x) = cos(cos(x)) * (-sin(x)) * (1)
Um... Maybe. Like I said, I could be (and likely am) wrong...
Heh, 3 years of calc, and I can't remember a damn thing. Thank you, beer!

The answer I got from people that are better at this than me was -sin(x) * cos(cos(x)), so the same thing that you got.
Guess it's time to dig out that calc book again.

I just want to make sure I am remembering this stuff right so that I don't mess my entire week up as I go back trying to figure out what's wrong only to find it's this stuff
Ok thanks Govtcheez!
working on... finding... Maple...
ok... I can't locate a free download of it anymore, but it's useful for checking your derivatives/integrals... sorry... you could look around for a copy of it tho.
EntropySink. You know you have to click it.
I've never heard of it... does it work well?
ONce you figure it out, it's helpful. I never got the hang of it, though.

Hmmm... maybe I should write something to calculate derivative expressions like a TI-89 or Maple does
yeah, there's definately a learning curve, but when you can type in an equation and it spits out what you want.... you just can't beat it.

um... what about my TI-92?
