Front

Define a coterminal angle.

Back

Coterminal angles are angles that share the same terminal side when drawn in standard position. They can be found by adding or subtracting multiples of 360° (or 2π radians).

Front

What is the unit circle?

Back

The unit circle is a circle with a radius of 1 centered at the origin (0,0) in the coordinate plane, used to define trigonometric functions.

Front

What is the sine of an angle in the unit circle?

Back

The sine of an angle is the y-coordinate of the point on the unit circle corresponding to that angle.

Front

What is the cosine of an angle in the unit circle?

Back

The cosine of an angle is the x-coordinate of the point on the unit circle corresponding to that angle.
