Trigonometry L1-4 Definitions of Trigonometric Functions r y θ x
Ex1. Find the six trig functions for the angle whose terminal side passes through (4,-2). 4 θ -2 r 42 + (-2)2 = r2
Ex2. Find the six trig functions for the angle θ that terminates in QIII and sinθ = -2/3. θ -x (-2)2 + x2 = 32 -2 3
Ex3. Find the six trig functions for the angle θ = 135˚. Reference angle is 45˚ in Q2 Ex4. Find the six trig functions for the angle θ = 270˚.
