Does anyone know how to use the Maple Software?

[ilikephysics]

The instructions for the attached hw instructs us to use maple for both problems. I really don't know how to use it. I've never really used it. Can someone help please?

Everything you need should be in Maple's online help files. Look up series and plot and so on.

I'm still a bit confused of how to do legendre polynomials. For #1, I have to expand the function sin(x) in a series of legendre polynomials Pn(x) on the interval x E [-1,1]. Would I do this like the taylor series, x-x^3/3!+x^5/5!-x^7/7!+...

So would P0(x) be x, P1(x)=x^3/3!, P2(x)=x^5/5!, P3(x)=x^7/7!

Still don't know how to plot it..

Can someone please help me? I tried #1. Is it right? Am I on the right track?
