# Math Help - Finding a norm

1. ## Finding a norm

I need some assistance in finding ||x^2|| using both the Laguerre and the Legendre inner products.

So in your question, I guess if x=(x,y) then $x^2 = (x^2,y^2)$. You know that if $x^2$ is an inner product space the norm is defined by $\|x^2\| = \sqrt{\left\langle x^2,y^2 \right\rangle}$.

3. I am aware of that, but I am confused on how to utilize the Legendre, and in a separate section, the Laguerre, inner products to determine the answer.
