Homework Statement
A Givens rotation is a matrix J(i,k) that is the identity matrix except jii = jkk = c and jik = -jki = s where c2 + s2 = 1. Let x = [1,-1,3]T. Find the rotation matrix J(2,3) such that the third element of Jx is zero. Show that J(2,3) is orthogonal.
Homework Equations
To prove orthogonality just show JTJ = I
