what is rad?
the derivative of the inside is (.5)(3(-sinx)^2)^-1
I mean the derivative of the whole thing
on the outside is it -1/2?
wait no type.. it is (.5) ((-sinx)(3(cosx)^2))^-1/2
The constant term is -1/2 and the whole second part should be in the denomenator
okay so when you chan the radical, you do the derivative of the cos. and in finding the derivative of cos, you have to chain it again?
yes its a whole bunch of chains.
haha, okay. are you taking ap test?
Ya i am.. taking BC calc
did you take the AB last year?
the test i mean
No i just flexed it.
I learned all of this in like middle school, and then now I'm just testing out of it so I can take college next year. calc 3 = fun
haha. cool. i'll take the AB test next week. =] good luck with everything !
yep you too.
Ya I was wrong again.. use http://www.wolframalpha.com/input/?i=%28cos^3x%29^.5
i didn't know you could use u sub for derivatives...
They use it for the chain rule, but most of the time you don't see it.,
