Problem 165

Consider \(\mathbf{u}=\langle a, b, c\rangle\) a nonzero threedimensional vector. Let \(\cos \alpha, \quad \cos \beta\), and \(\cos \gamma\) be the directions of the cosines of u. Show that \(\cos ^{2} \alpha+\cos ^{2} \beta+\cos ^{2} \gamma=1\).

Text Transcription:

u = langle a, b, c rangle

cos alpha, cos beta

cos gamma

cos^2 alpha + cos^2 beta + cos^2 gamma = 1
