Surely you can make a start? They have given you a function I so the first step is to differentiate it (and then a second time)

Someone sent me the solution but I just don't know how they got there.

OK, but can you make a start on the differentiation? What do you get for dI/dt?

You have a product of 2 functions so you need to use the product rule to differentiate - does this ring any bells? Also you've brought out a 't' factor when I would expect either an 'a' or a 'w'

I've now done the second derivative. What does it mean when it says "show that I(t) is a solution of equation 1"?
