Hello, Can you please help me figure this out? Let <u,v> be the inner product on R2 generated by [ 2 1 ] [ 1 1 ] <u+v,w> u = (2,1) v = (-1,1) w = (0,-1) .... I keep getting -2 is my answer, but the book states that it should be -7

I get that too. However, your post says inner product and this is the dot product. Do you have an inner product definition for this?
I found this in the book, but i'm sure how to apply it: <u,v> = (Av)^T Au
Do the same for the other one and add.

Thanks! I was also wondering....how do you evaluate this? || v - w ||^2 i just wanna see how its written out.
<v-w,v-w>=||v||^2-2||v||||w||+||w||^2
thanks!
