Find The Exact Value Of Each Trigonometric Function Worksheet 0 0 0 infty Remember that all trigonometric functions have a periodicity of 2 pi 2 this means that for every angle alpha the exact calculated value of the trig function f f satisfies the rule f alpha f 2k pi alpha f f 2k where k k is any integer number Next you can find the exact value
The calculator instantly tells you that sin 45 0 70710678 It also gives the values of other trig functions such as cos 45 and tan 45 The second section uses trigonometry to determine the missing parameters of a right angled triangle First select what parameters are known about the triangle Section 1 3 Trig Functions Determine the exact value of each of the following without using a calculator Note that the point of these problems is not really to learn how to find the value of trig functions but instead to get you comfortable with the unit circle since that is a very important skill that will be needed in solving trig equations
