### Exact trig values at a glance

The sin, cos and tan of certain angles are exact values rather than decimals. The exact trigonometric values of sin, cos and tan are:

Knowing the exact values of sin, cos and tan allows us to use the trigonometric functions without using a calculator for certain angles.

These values can be found by applying the trigonometric ratios of sin, cos and tan to two special triangles:

For example, using the trig ratio sin(x) = opposite/hypotenuse we get sin(45) = 1/square root of 2.

Applying each of the trig functions to these triangles will give the exact trig values for 30o, 45o and 600

Looking forward, students can then progress to additional geometry worksheets, for example an or
