WebNov 16, 2024 · 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. cos(5π 6) cos. . ( 5 π 6) Solution. sin(−4π 3) sin. . The values of trigonometric numbers can be derived through a combination of methods. The values of sine and cosine of 30, 45, and 60 degrees are derived by analysis of the 30-60-90 and 90-45-45 triangles. If the angle is expressed in radians as , this takes care of the case where a is 1 and b is 2, 3, 4, or 6. If the denominator, b, is multiplied by additional factors of 2, the sine and cosine can be derived …
