  3. u = 4i - 2j tan( u ) = - 2/4 = - 1/2 → angle_ u = - 26.565° v = i + 3j tan(v) = 3/1 = 3 → angle_v = 71.565° angle between u and v: = 71.565 - (- 26.565) = 71.565 + 26.565 = 98.130°

  10. Express 1 as a fraction: ( -2/(5u+10) ) - (5u+10)/(5u+10) = 2/ ( u +2) Subtract fractions on left side: (-2-5u-10)/(5u+10... of the original equation. So the only answer is u = -4.4.
