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 is

[NOTE: 1 – cos x = 2 sin²(x/2)]

Formula used: = 1

So, by using the above formula, we have

=

Divide numerator and denominator by x², we have

= = = = =

[NOTE: = ]

Therefore, =
