1. The problem statement, all variables and given/known data See Attachment. Help with b) c) will be appreciated. 3. The attempt at a solution For the third question, my approach is sub in values for a and b which correspond to the co-effs. of the given basis. Then assemble a matrix from them. Eg: f[(5,0);(1,3)]=[(1,1);(2;-1)] which gives me [(-17,4);(15,-3)] for c). Any help is appreciated.
