What is 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 2π (360 degrees) to the original angle.

Front

Find one positive and one negative coterminal angle to 5π/4.

Back

Positive: 13π/4, Negative: -11π/4.

Front

What is the relationship between sine and cosine in a right triangle?

Back

Sine is the ratio of the opposite side to the hypotenuse, while cosine is the ratio of the adjacent side to the hypotenuse.

Front

What is the formula for finding the amplitude of a sine function?

Back

The amplitude is the absolute value of the coefficient in front of the sine function.
