Front

What is the reference angle for -5π/4?

Back

π/4

Front

What is the equation of the midline for a sinusoidal function?

Back

y=3

Front

What is the reference angle for 120°?

Back

60°

Front

What is the period of a function with a period of 8?

Back

8

Front

Define vertical asymptote in trigonometric functions.

Back

A vertical asymptote is a line x = a where a function approaches infinity or negative infinity.

Front

What is the range of the sine function?

Back

[-1, 1]

Front

What is the amplitude of a sinusoidal function?

Back

The amplitude is the maximum distance from the midline to the peak or trough.

Front

How do you find the reference angle in radians?

Back

The reference angle is the acute angle formed by the terminal side of the angle and the x-axis.

Front

What is the relationship between sine and cosine?

Back

Sine and cosine are co-functions; sin(θ) = cos(90° - θ).
