What is a horizontal shift in a trigonometric function?

Back

A horizontal shift refers to the movement of the graph left or right along the x-axis. For example, a shift left by π means the function is evaluated at (x + π).

What is a vertical shift in a trigonometric function?

Back

A vertical shift refers to the movement of the graph up or down along the y-axis. For example, a shift down by 3 means the function is evaluated as f(x) - 3.

Front

What does the variable 'k' represent in a sinusoidal function?

Back

The variable 'k' affects the frequency of the function. A larger value of k results in more cycles in a given interval.

What is the unit circle?

Back

The unit circle is a circle with a radius of 1 centered at the origin (0,0) in the coordinate plane, used to define trigonometric functions.
