Hello every one. I hope everything is going well and every one finds the answer to their questions. I hope to be a helpful member of this comunity although at first I imagine that I will be asking more questions that answering.

I have an interst in general mathmatics but no formal trainning in the subject. I also have an interest in applications of the math that I learn (some applications that might be more useful and some that are mostly for fun).

The first questions I have are about Fourier Transforms, FFT, and there applications. Where would I post such questions? Can I post images in a post? Is there help for the forums?

Like I said above, I will problably have more questions that answers for now but maybe some of the questions and answers will be useful for some one else.
Thank you and have a good time.
