Is that correct so far? And any advice for what to do after...I've never done a question like this and it's confusing me!

Thanks..I'm trying to work it out.

Am I on the right track or way off base? - Nov 23rd 2010, 12:10 PMPlato
You missed a is the last term.

Now multiply all by y. - Nov 23rd 2010, 12:12 PMe^(i*pi)
I don't understand your last term. Given that

In your case

Rest of it is fine though, remember that you made a y sub when multiplying by y. - Nov 23rd 2010, 02:23 PMGoose
Thanks so much for the help :)

I think I have the solution figured out now.

But you must follow your instructions.
