(Chapter 1: Review) 1.27 PART C: COTERMINAL ANGLES Standard angles that share the same terminal side are called coterminal angles . They differ by an integer number of full revolutions counterclockwise or clockwise. If the angle ± is measured in radians , then its coterminal angles are of the form: + 2 ² n , where n is any integer. If the angle is measured in degrees , then its coterminal angles are of the form: + 360 n ± , where n is any integer. Note : Since n could be negative, the “+” sign is sufficient in the above forms, as

Unformatted text preview: opposed to “ ± .” PART D: TRIG FUNCTIONS: THE RIGHT TRIANGLE APPROACH The Setup The acute angles of a right triangle are complementary. Consider such an angle, . Relative to , we may label the sides as follows: The hypotenuse always faces the right angle, and it is always the longest side. The other two sides are the legs . The opposite side (relative to ) faces the angle. The other leg is the adjacent side (relative to )....
