ok?

It's actually (x->0.)

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

Lim [cot(x) - csc (x)]

..x->0

= Lim [(cos x -1)/sin x]

..x->0

Use L'Hopital's rule and take the ratio of the derivatives:

Lim (-sin x/cos x) = 0

x->0

thank you very much...it helped alot :)

so the answer would be zero?

No problem.

I'm happy to help you.
