For each n, write in terms of polar coordinates . So , . (For n=0, take .) Then .
I am having some trouble with the following problem:
Show that the Fourier series:
can be written in the form
where . Express in terms of and .
Ok so I got down to the fourier series being equal to this:
which is not exactly what we want especially the .
Also any idea how to do "Express in terms of and ."???
I thought that in a Fourier Series the coefficients had to be:
So can I still just rewrite the way you show me??? Sorry I am just trying to make sure I have a good understanding of it all.
Also to express in terms of and , I am guessing it would be something like:
