Rhea Section for MA 35100 Professor Kummini, Spring 2011

Can someone help me in the question number 16 from section 5.1 I am not able to understand what will be the condition for the vectors to be orthonormal.

Did you mean orthogonal? I believe the problem said that the vectors had to be orthogonal. In order for that to be true, you have to do the dot product between all four vectors and it must equal zero. To start it, I just created a new 4x1 vector with four different variables, and made did the dot product and set it equal to zero. From there, you can figure out the vectors you need to solve for.
