1 Section 1.4 Trigonometric Functions an ANY Angle Evaluate trig functions of any angle Use reference angles to evaluate trig functions

2 Unit circle = opp hyp Cos  = x Tan  = y/x Csc  = 1/y Sec  = 1/x Cot  = x/y Sin  = y = hyp opp = adj hyp = hyp adj = opp adj = adj hyp Right Triangles = y r = x r = y x = r y = r x = x y

3 Find the 6 trig functions given the point (-3, 4) Sin  = Cos  = Tan  = Csc  = Sec  = Cot  =

4 Find the 6 trig functions given the point (-9, -40) Sin  = Cos  = Tan  = Csc  = Sec  = Cot  =

5 Find the 6 trig functions given the point (5, -2) Sin  = Cos  = Tan  = Csc  = Sec  = Cot  =

6 Find the values of the six trig functions when— – Cosθ = -4/5 and θ lies in quadrant III

7 Find the values of the six trig functions – Cos θ = 8/17 and tan θ < 0
