Unit Circle Revisited - Example 3

A trigonometric function is a function of an angle. The angle may be in radians or in degrees. The trigonometric functions are commonly defined for angles in the range –90° to +90°. The commonly-used trigonometric functions are sine (sin), cosine (cos), tangent (tan), cotangent (cotan), secant (sech), and cosecant (cosech). The inverse trigonometric functions are the arcsine (arcsin), arccosine (arccos), arctangent (arctan), arccotangent (arccotan), arcsecant (arccosec), and arc cosecant (arccosech).

in standard form, which means it's within our unit circle and we want to find the sun of this angle and the cosign. Now we can find this from the X Y coordinates of a given point and are given point is P where X is negative one half and why is square root of three over to our sign is always gonna be r y coordinate. So that's gonna be our square root of three over to, and our Kosan will be our X coordinate, which is negative one over to.
