Homework Help: Calculus

yes! tnk u


It's actually (x->0.)

Find the limit of cot(x)-csc(x) as x approached 0?

Lim [cot(x) - csc (x)]
= Lim [(cos x -1)/sin x]
Use L'Hopital's rule and take the ratio of the derivatives:
Lim (-sin x/cos x) = 0

thank you very helped alot :)

so the answer would be zero?

No problem.
I'm happy to help you.
