Trigonometry

Amplitude, Period, and Frequency

How the numbers inside a sine function control its shape.

Applications of Trigonometric Graphs

Real-world phenomena repeat on a schedule — sine and cosine are how you describe them.

Graphing Sine and Cosine

How amplitude, period, and midline shape every wave.

Graphing Tangent

A function that grows without bound — and breaks at regular intervals.

Shifts in Trigonometric Graphs

How adding constants inside and outside a trig function moves the entire wave.
