^{2}defined by the inner product below?

f(

_{1}v

_{1}+ 4u

I thought about finding the integral for the square of the expression but am otherwise drawing a blank.

What is the expression for the norm on R^{2} defined by the inner product below?

f(**u**, **v**) = 7u_{1}v_{1} + 4u_{2}v_{2}

I thought about finding the integral for the square of the expression but am otherwise drawing a blank.

What definition did they give you for the norm? I'm not familiar with a definition that uses integrals. I'm used to stuff more like this. Thanks!What is the expression for the norm on R^{2}defined by the inner product below?

f(u,v) = 7u_{1}v_{1}+ 4u_{2}v_{2}

The notes I have say to use the Euclidean norm if the problem merely says to find the norm.

Okay. How does your book's definition of "norm" differ from what was at the link I gave (or this other link)? Thanks!
