Sin and Cos Graphs (identify) plus read period

Front

What is the sine function?

Back

The sine function, denoted as sin(x), is a trigonometric function that relates the angle of a right triangle to the ratio of the length of the opposite side to the hypotenuse.

Front

What is the cosine function?

Back

The cosine function, denoted as cos(x), is a trigonometric function that relates the angle of a right triangle to the ratio of the length of the adjacent side to the hypotenuse.

Front

What is the amplitude of the sine function?

Back

The amplitude of the sine function is the maximum value of the function, which is 1 for the standard sine function.

Front

What is the amplitude of the cosine function?

Back

The amplitude of the cosine function is the maximum value of the function, which is 1 for the standard cosine function.

Front

What is the effect of a negative sign in front of the sine function, y = -sin(x)?

Back

The negative sign reflects the sine graph across the x-axis.

What is the effect of a negative sign in front of the cosine function, y = -cos(x)?

Back

The negative sign reflects the cosine graph across the x-axis.
