1 AnswerMathematics1 decade agoLimit definition, derivative of sec?
I've been spending too much time trying to put it all together, could someone please help to prove (using limit definition h--->0) that d/dx (sec x) = sec x tan x.
Thanks so much, I am unable to see how to fit together all the identities using the limit definition.

lim x--->positive infinity (2^x-3^-x)/(2^x+3^-x)
I can graph it and it looks to be approaching +1, can't figure out how to solve it though? Please explain thoroughly. All help appreciated!
2 AnswersMathematics1 decade agoDerivative of cos^2(x^2-2)?
A little unsure on how to do this one. Would I have to combine the chain and product rules? If so, the answer would be (2cos)(-sin)(x^2-2)+(2x)(cos^2)?? Is that anywhere near correct? Thanks.
