Please,help is very much appreciated...
I am required to solve this second order ODE :
y"(x)-3y'(x)-2y(x)=sinh(x)
....using the Variation of Parameters method.
The final answer is EXTREMELY complicated,and i have no idea how to get to that answer.Its too long to be typed here.Would really appreciate the help.thanks.
Note: it is a parabolic sinh(x) , not just sin(x).
