Graphs of Trigonometric Functions (Edexcel A-Level Mathematics): Flashcards

The period is $360°$ (or $2\pi$ radians).

The amplitude is $1$.

At $x = 90°, 450°$, where $y = 1$.

It's a smooth, continuous wave.

The period is $360°$ (or $2\pi$ radians).

At $x = 180°, 540°$, where $y = -1$.

The period is $180°$ (or $\pi$ radians).

At $x = 90°$ and $270°$ (vertical asymptotes).

$A$ affects the amplitude of the graph.

It changes the period to $360°/B$.
