Find two vectors of norm 1 that are orthogonal to the vectors u =
w = (3,2,5,4).
(2,1, –4,0), v = (-1,-1,2,2), and
19.
Find the standard matrix for the linear operator T:R³ → R³ that first rotate a vector counterclockwise
about the y-axis through an angle 0 = 60, then reflect the resulting vector about the xz -plane, and
then transform the resulting vector by the formula T(x,y,z) = (2x – 3y + 4z, –3x + y – 2z,x +
3y). Hence compute T(1, –2,1).
