i resolved it no help needed

trying not suceeded

still working on it

am I correct?

Thanks. I'll try and post back my findings.

Homework Statement Let s be the linear transformation s: P2→ R^3 ( P2 is polynomial of degree 2 or less) a+bx→(a,b,a+b) find the matrix of s and the matrix of tos with respect to the standard basis for the domain P2 and the standard basis for the codomain R^3 The Attempt at a...

Number 4 post is about orthogonal vectors? Is that the one you want me to look at?

Ok - thanks.

That's what I am not sure of. How might you do it?

Apologies if this still seem like a homework question- I am happy for you to move it- if that's the case

here it is - its in a word document formate hope you can read it. You'll see that there is a problem and answer - which I fail to understand

i see if I can paste a image of textbook here

oh no- its not a home work question- I am studying pur mathematics and this is one of the explanation - where they straightaway gave matrix- but I am not sure how do you arrive at it. this part of the book covers composite matrix- so like in this one if one is s and another one is t , what would...

oh sorry - its polynomials of degree 2 and 3 p(x) = has standard basis {1,x,x^2} = a+bx+cx^2 and p'(x) is its derivatives. Hope I am making sense
