Understanding Sine

The sine of an angle in a right triangle is the ratio of the length of the opposite side to the length of the hypotenuse. In a unit circle, the sine of an angle is the y-coordinate of the point where the terminal side of the angle intersects the circle.

Radians vs. Degrees

Degrees and radians are two units for measuring angles. A full circle is 360 degrees or 2π radians. The conversion between degrees and radians is: radians = degrees * (π / 180).
