Unit Circle Revisited - Example 4

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).

point p, which is the coordinates 0.6 and 0.8 to find the sign and co sign of an angle that is drawn you with this point. Uh, this point is actually going allow the terminal side of the angle, which means, um that it's the side that's moving and it's gonna that means there's gonna be an r. It would equal one. We can get our sign and cosign from our points. Our son is r y coordinate. So that's gonna be 0.8 and our cosign is our X coordinate, which will be 0.6.
