A time-dependent torque given by a + bsin(ct) is applied to an object that's initially stationary but is free to rotate. Here a, b, and c are constants. Find an expression for the object's angular momentum as a function of time, assuming the torque is first applied at t = 0.
∫a +bsin(ct) (from 0 to infinity )
τ = dL / dT
The Attempt at a Solution
Not really sure where to start, since I really don't have much experience with these types of problems. I think that this is an infinite integral problem, at least, since it only defines one point in time. Can anyone point me in the right direction? Thanks!
