Hi! can some explain how to evaluate these two questions, so that i can understand how to complete them?
1. given: cos∅= -4/5, sin x= -12/13, ∅ is in the third quadrant, and x is in the fourth quadrant; evaluate cos(theta - x).
2. given: sin∅= -3/5, ∅ is a third quadrant angle, and tanф= -7/24, ф is a second-quadrant angle; find tan(∅+ф).
you for your !
