I was wondering if 18.4 will be tested on the final? I have tried some of the questions and they are hard. If they are on the final do you have any answers to the questions?
18.4 is potentially in.
Hi! It would be really helpful if there were solutions to section 18.4... would you be able to post these? If not could you just give me a hint on Q:2 What do I do once I have found expressions for C2n and C2n+1 in order to get an expression for Y and Y'??
There is no need to separate even from odd indices here; there will be one constant at the end, C0, since it is a differential equation involving the first derivative only. Do it carefully and if you are stuck then it wold help if you know exactly where you encounter a problem.
I do not have solutions of 18.4.
