Understanding Cosine
The cosine of an angle in a right triangle is the ratio of the length of the adjacent side to the length of the hypotenuse. In a unit circle, the cosine of an angle is the x-coordinate of the point where the terminal side of the angle intersects the circle.
Radians vs. Degrees
Angles can be measured in degrees or radians. A full circle is 360 degrees or 2π radians. The conversion is: radians = degrees * (π / 180).
