Can someone help me revise how to do these...

x^4cos(x^2)

tan(x)/1+x^3 - quotient rule

sin(exp(1+x^2)) - chain rule?

hi just looking over this again, could someone just check that example three is correct?

So http://www.mathhelpforum.com/math-he...2ac815e7-1.gif,

I get it up to here..

but below where does sin come from in the last part? should it not be cose^1+x^2...

hey ppl ..... just joined this forum a lil while ago and i'm impressed by what i've seen so far. although i havent done calculus since 5 years ago (so i'm really really rusty! ) but just looking at the recent posts brings back some wonderful memories.

amm .... i'm new to all of this but can someone tell me how to get the different mathematical symbols when posting? i mean like how to get the dy/dx or integral sign, exponent, fractions etc. is there a clipboard on the forum with the symbols on it or are they from an external program or what?

thanks (Hi) - Aug 15th 2008, 12:50 AMProve It
