Let alpha and beta be angles such that P is the terminal point for alpha and Q is the terminal point for beta.

Say that cos(alpha) = 12/13 and cos(beta) = -4/5

Then, if R = (r_1, r_2), and S = (s_1, s_2), enter r_1, r_2, s_1, and s_2.

b) If T = (t_1, t_2), and U = u_1, u_2), enter t_1, t_2, u_1 and u_2

Please show steps. :)

\((r_1, r_2, s_1, s_2) = (-3/5, 4/5, -24/25, 7/25)\)

\((t_1, t_2, u_1, u_2) = (144/145, -7/145, 9/41, -40/41)\)
