Unit Circle Revisited - Example 1

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).

and cosign. Oven angle in standard form. Given the point, P and the coordinates four point p. R. Negative three fists and for fists. Now, these air, because they're a standard form their unit circle, which means that the are on all of these equals one so we can find our son and cosign from our coordinates. Our son of this angle is going to be our y coordinate. So in this case, that's going to be four Biss and our co son of this angle is our X coordinate, which is negative three this.
