## Homework Statement

For spherical coordinates, we will need to use Legendre Polynomials,

a.Sketch graphs of the first 3 – P0(x), P1(x), and P2(x).

b.Evaluate the orthogonality relationship (eq 3.68) to show these 3 functions are

orthogonal to each other. (3 integrals).

c.Show that the normalization result is 2/2l+1 as stated in eq 3.68.

## Homework Equations

## The Attempt at a Solution

I believe I got part a, but I am unsure how to do the rest. I don't see where the equation that has the theta terms, comes in to use.
