COMPOUND ANGLE FORMULAS Recall the unit circle: r=1 y y (cos ,sin ) x x compound angle: an angle that is created by adding or subtracting two or more angles Determine a formula for calculating cos(a – b) using the given diagram: Using Cosine Law: c 2 = a 2 + b ...
(i) In the above proof, PR = SQ says that the distance between two points on a circle is determined by the radius and the central angle. (ii) Arcs PR and SQ subtend anglesα + β andα + (-β) respectively at the center. Thus PR = SQ. Thus, distance between the points (cosα...
