## NCERT Exercise 7.1

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

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

Solution:

Given, *cos3x*

Since,

Thus, antiderivative of

**Alternate method:**

Thus, antiderivative of

Therefore, antiderivative of

**Alternate method:**

Therefore, antiderivative of

Therefore, antiderivative of

**Alternate method:**

Therefore, antiderivative of
