Answer :
Given differential equation is
………eq(1)
Equation (1) is of the form
Where, and
Therefore, integrating factor is
………
General solution is
………eq(2)
Let,
Let, u=sin x and v=e2x
………
………
Again, let u=cos x and v=e2x
………
………
Multiplying above equation by 4,
Substituting I in eq(2),
Dividing above equation by e2x,
Therefore general equation is
