(adsbygoogle = window.adsbygoogle || []).push({}); 1. Let W be the linear subspace spanned by the polynomials 1 and x. Find an orthogonal projection of the polynomial p(x) = 1+x^2 to W. Find a basis in the space W(perp)

My problem is that I don't know how to represent W as a matrix so that I could apply the orthogonal projection formula.

Would it simply be [1, x] or [1 ; x]?

Thanks!
