Question
2. Show that matrix multiplication distributes over matrix addition: show A(B + C) = AB+ AC assuming that A, B, and C are matrices of compatible size. 3. Write a function my_is_orthogonal (v1,v2,tol) where v1 and v2 are column vectors of the same size, and tol is a scalar value strictly larger than zero. The output should be 1 if the angle between vl and v2 is within tol of 1/2, that is, |7/2 – 0| < tol, and zero otherwise. You may assume that vl and v2 are column vectors of the same size, and that tol is a positive scalar.
