# Math Exam Resources/Courses/MATH152/April 2016/Question A 07 Hint

Hey,

I understand your hint and solution, but would you mind writing a more detailed hint? Would it be more clear that if we just say " recall that A(:, i) returns the ith column of the matrix A"?

Thanks!

Aili

I guess the write thought it is too direct hint, but I agree with you. It is revised!
