The unit circle definition allows us to extend the domain of sine and cosine to all real numbers The process for determining the sine cosine of any angle is as follows Starting from 1 0 move along the unit circle in the counterclockwise direction until the angle that is formed between your position the origin and the positive Noble Mushtak cos 2 sin 2 1 where has the same definition of 0 above This is similar to the equation x 2 y 2 1 which is the graph of a circle with a radius of 1 centered around the origin This is how the unit circle is graphed which you seem to understand well

This will be studied in the next exercise Exercise 1 1 2 1 1 2 The following diagram is a unit circle with 24 24 points equally space points plotted on the circle Since the circumference of the circle is 2 2 units the increment between two consecutive points on the circle is 2 24 12 2 24 12 In mathematics the unit circle is a circle with a radius of one centered at the origin 0 0 of a two dimensional Cartesian coordinate system It is commonly used to measure angles in trigonometric functions sine cosine and tangent as well as in geometry and other related areas of mathematics
