Exact trigonometric values table
WebJun 8, 2024 · To find the trig value of a particular angle, you start by putting down the finger for that angle. So, for 30° that would be your index finger. For sin, count how many fingers are above that finger, square root it and divide it by 2. For sin (30°) there is one finger above so: For cos, count how many fingers are below that finger, square root ... WebExact trigonometric ratios for 0°, 30°, 45°, 60° and 90° ...

The trigonometric functions of angles that are multiples of 15°, 18°, or 22.5° have simple algebraic values. These values are listed in the following table for angles from 0° to 90°. For angles outside of this range, trigonometric values can be found by applying the reflection and shift identities. In the table below, … 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 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. Such numbers are called constructible, because one length can be constructed by compass and straightedge 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 $${\displaystyle \sin(x)=\cos(x-\pi /2),}$$ the case of a sine can be omitted from this definition. Therefore any trigonometric … See more The values of trigonometric numbers can be derived through a combination of methods.
