Find two orthogonal vectors in the plane containing the points A(-5,3,-4) B(-4,-3,-1) and C(-2,5,3)
Ok so i have that
AB = <1,-6,3>
AC = <3,2,7>
AB X AC = n = determinant of the 3x3 matrix = -48i + 2j +20k
so i need u and v such that u . v = 0 and u . n = 0 and v . n =0
i have a feeling it should be easy but i can't figure it out?
