Thus, Sin 180o = 0/1 = 0 and Cos 180o = -1/1 = -1 3) Find the Sin 540o and Cos 540o Solution: Since the angle 540o has the same terminal side as 180o, the Sine and Cosine functions have the same value as problem # 2. This leads to the conclusion that the trig functions repeat their value every 360o or 2 Conclusion: Sin ( + 360o) = Sin Cos ...
