I'm having a bit of trouble with a diff equation, I've never dealt with anything quite as complicated as it before and have no idea what to do.
I've been given the equation , and also the general solution
What i have to do is find in terms of k, b and m. I've never dealt with a 2nd order diff equation where x(t) isn't simply so I don't really have a clue what to do. I tried calculating the derivatives of x and substituting them into the diff equation, but i couldn't seem to rearrange the thing to look anything like the general solution of x.
Any help would be greatly appreciated,
EDIT: What i have to do is find
