Front

What is the sine function?

Back

The sine function is a trigonometric function that relates the angle of a right triangle to the ratio of the length of the opposite side to the length of the hypotenuse. It is defined as sin(θ) = opposite/hypotenuse.

Front

What is the range of the sine function?

Back

The range of the sine function is from -1 to 1, meaning that the output values of the sine function can only be within this interval.

Front

What is the sine of 120 degrees?

Back

The sine of 120 degrees is approximately 0.866.

Front

What is the sine of 240 degrees?

Back

The sine of 240 degrees is -0.866.

Front

What is the relationship between sine and the unit circle?

Back

On the unit circle, the sine of an angle corresponds to the y-coordinate of the point where the terminal side of the angle intersects the circle.

Front

What is the sine graph's periodicity?

Back

The sine graph is periodic with a period of 360 degrees, meaning it repeats its values every 360 degrees.

Front

What is the height of a Ferris wheel at 30 degrees if the height above the platform is 0.5 units?

Back

At 30 degrees, the height above the platform is 0.5 units.

Front

What angle on the Ferris wheel will also have a height of 0.5 units above the platform?

Back

The angle of 150 degrees will also have a height of 0.5 units above the platform.

Front

What is the cosine function?

Back

The cosine function is a trigonometric function that relates the angle of a right triangle to the ratio of the length of the adjacent side to the length of the hypotenuse. It is defined as cos(θ) = adjacent/hypotenuse.

Front

What is the cosine of 30 degrees?

Back

The cosine of 30 degrees is approximately 0.866.
