Q5. (a) Find the value of lambda, for which the following differential equation will be an exact DE:

(xy^2+2*lambda*x^2y)dx+(x+y)x^2dy=0
(b) Find it’s general solution once you find a value of lambda in (a).
(c) Use the inverse operator method to solve the following non-homogeneous ODE:

y''+2y'+4y=e^2x*cosx

Q5. (a) Find the value of 2, for which the following differential equation will be an exact DE:
