    Solve 2nd Order Diff Eq: (-1/k^2)*(d^2y/dx^2)-y = (Q*c/P*L)*x

    rock.freak667 I am reviewing that website and will continue on this post once I have a better understanding of second order differential equations. Maybe I jumped in the deep end of the pool not ready for no solid ground to stand on. Simon, your suspicions are correct, I will refer back to these...

    Solve 2nd Order Diff Eq: (-1/k^2)*(d^2y/dx^2)-y = (Q*c/P*L)*x

    ehild, I am trying to learn the steps to get to the solution "y = A*cos(k*x) +B*sin(k*x) -(Q*c/P*L)*x". I should have mentioned that I haven't had the need to do diff eq's in over 6 years and now I'm learning everything over again to understand a book I'm reading that utilizes equations like...

    Solve 2nd Order Diff Eq: (-1/k^2)*(d^2y/dx^2)-y = (Q*c/P*L)*x

    Homework Statement Hi everyone, I have the following differential equation that I am trying to solve: (-1/k^{2})*(d^{2}y/dx^{2}) - y = (Q*c/P*L)*x Where Q,c,P,L, and k are constants. The solution ends up being: y = A*cos(k*x) +B*sin(k*x) -(Q*c/P*L)*x Where A and B are constants...
