Consider the first-order linear differential equation \(y'+p(t)y~=~q(t),~~~'=\frac{d~}{dt}\) where the functions p and q are continuous in an open interval \(I=(\alpha ,\beta )\) [1]. We can find the general solution of (1.1) in terms of the known functions p and q by multiplying both sides of (1.1) by an integrating factor \(e^{P(t)}\), where P(t) is a function such that \(P'(t)=p(t)\).
