Evaluate the following limits:

To Find: Limits

NOTE: First Check the form of imit. Used this method if the limit is satisfying any one from 7 indeterminate form.

In this Case, indeterminate Form are

cosec 2x – cot 2x = (1 – cos 2x)/sin 2x

= = =

Formula used: = 1/2 and = 1

= = =

Therefore, =
