Integration : Problem 1

Problem :


Solution:

For this problems, we use Euler Substitutions,
Substitute, =
= —(1)
=
=
=
= —(2)
= —(3)
From (2) and using the quotient rule of differentiation,
=
Plugging these in the given problem we get,
=
=
=
=
=
=
Put value of from equation (1) and get the answer.
