AP Style MCQ Unit 3

Flashcards covering key vocabulary and concepts from the multiple-choice questions.

Periodic Function

A function that repeats its values in regular intervals or periods.

Period

The horizontal distance required for a periodic function to complete one full cycle.

Cosine

The measure of the horizontal displacement of a point from the y-axis.

Sine

The measure of the vertical displacement of a point from the x-axis

Tangent

The ratio of the vertical displacement to the horizontal displacement.

Sinusoidal Functions

Functions written in the form f(x) = a * sin(bx - c) + d or f(x) = a * cos(bx - c) + d, where a, b, c, and d are constants.

Amplitude

The vertical distance from the midline to the maximum or minimum value of the function.

Midline

A horizontal line that passes through the middle of the graph, halfway between the maximum and minimum values.

Vertical Asymptotes

Lines on the graph x = a where f(x) approaches infinity or negative infinity.

Inverse Sine Function

The angle whose sine is a given number.

Inverse Cosine Function

The angle whose cosine is a given number.

Inverse Tangent Function

The angle whose tangent is a given number.
