I'm a bit stuck on these questions about damped oscillations. It's actually from a physics course but the question is very maths based.
I'm basically stuck (well can't do) sections a) b) and c). Normally I can do differentiation but this one is a real beast. I've tried doing the basic stuff in part a) (produce rule and all that) but i'm getting no where and end up with a huge equation which i don't know if its right or not. I must be doing something wrong.
Any help would be greatly appreciated!
