This equation comes as we try to solve for the trajectory of a man walking on a rotating disc. We can surely solve it numerically, but I was wondering if there are any closed form solution to this. Python SymPy fails to do it. dR/dt = v*sin(phi+theta) d(phi)/dt = (v/R)*cos(phi+theta)+w R (radial location) and phi (angle) are functions of time t. v, theta and w are constants. Please let me know if you would need more information.
