## NCERT Exercise 7.1

Find an anti derivative (or integral) of the following by the method of inspection:

Question:

Solution:

Given, *sin2x*

To find out the antiderivation we have to find out a function whose derivation is *sin2x.*

Therefore, antiderivaion of

Alternate method:

Therefore, antiderivaion of
