Deriving relation between angular momentum reduction by torque

W = integral of (torque x dθ) = Iω^2 / 2
Considering change in torque is difficult i guess. since Radial vector changes and the dθ is infact a tilt to backwards... so I guess we need a much complicated differential equation, isn't that so?
Change in torque is rather uncommon in such cases right? is this a case of change in acceleration-jerking. I've never seen an equation including jerking.
