# How do you simplify #(1 + sec theta)/sec theta = sin^2 theta/(1 - cos theta)#?

Please look at the explanation

Recall: The identities of trigonometry

#(1+sectheta)/sectheta = [cancel(sin^2theta) (1+costheta)]/(cancel(sin^2theta)#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
