Back

-1

Front

Define the period of a sine function.

Back

The period is the distance along the x-axis for one complete cycle of the wave, typically 2π for sine functions.

Front

What is the amplitude of y = -3sin(x)?

Back

3 (the amplitude is the absolute value of the coefficient of sin)

Front

What is the range of the function y = -3sin(x)?

Back

[-3, 3] (the maximum value is 3 and the minimum value is -3)

Front

What is the value of sin(0)?

Back
