From the class notes our gram schmidt process is diffrent , but after trying to use it on the {1,x,x^2,x^3} basis all i get is U1=1 U2=0 U3=0 ... and so forth .

i define U(1) = 1 U(2) = A*1 + B*x

so 0=(U(2),U(1)) = (A,1) + (B*x,1) = A +B*x , i choose B=1 so i get A=-x and there goes the endless loop of U(n)=0 for n>1

note : (x,y) - inner product space , just to clarify in case this forum signs it diffrently

help would be much appriciated
