Evaluate the following integrals:

To Find :

Now , consider =

=

=

=

Let x + = y dx = dy

Hence becomes

Formula Used: = log |x +|+ C

Now consider which is in the form of with change in variable.

= log |y +|+ C

= log |y +|+ C

Since x + = y and dx = dy

= log | +|+ C

Now , = log | +|+ C

Therefore,

= log | +|+ C
