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. 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 $${\displaystyle a\pi /b}$$, this takes care of the case where a is … See more In mathematics, the values of the trigonometric functions can be expressed approximately, as in $${\displaystyle \cos(\pi /4)\approx 0.707}$$, or exactly, as in $${\displaystyle \cos(\pi /4)={\sqrt {2}}/2}$$. … See more The trigonometric functions of angles that are multiples of 15°, 18°, or 22.5° have simple algebraic values. These values are listed in the … See more An irrational number that can be expressed as the sine or cosine of a rational multiple of π radians is called a trigonometric number. Since See more • Abramowitz, Milton; Stegun, Irene A., eds. (1972). Handbook of Mathematical Functions with Formulas, Graphs, and Mathematical Tables. … See more Some exact trigonometric values, such as $${\displaystyle \sin(60^{\circ })={\sqrt {3}}/2}$$, can be expressed in terms of a combination of arithmetic operations and square roots.
