Hi all. I am in the middle of a ridig body rotation problem. Anyways, I have x double dot = sin(x) and i need to find what x dot is. x is a function of time 't' and I just have no idea how to get it. so it is d^2x(t)/dt^2=sin(x(t)) where x(t) is a function and i need to find dx(t)/dt. Any help would be great, thanks!!
