The limit exists and is equal to #tan1#

Explanation:

The first step in calculating limits is to substitute the value #x# is going to and try to calculate the value. Only if this fails (you get symbols like #0/0# or #oo/oo#) you have to use some identities to transform the expression.

In this example if you substitute #1# you get #tan1/1# which equals #tan1#
