Trigonometric Functions (AQA A-Level Mathematics): Flashcards

$y = A\sin(x)$, $y = A\cos(x)$, or $y = A\tan(x)$

Graph is stretched vertically

Graph is reflected across the $x$-axis

$y = \sin(Bx)$, $y = \cos(Bx)$, or $y = \tan(Bx)$

$\frac{360°}{|B|}$ or $\frac{2\pi}{|B|}$

$\frac{180°}{|B|}$ or $\frac{\pi}{|B|}$

Graph shifts up by $C$ units

Graph shifts to the right by $D$ units

Graph shifts to the left by $|D|$ units

Graph compressed horizontally (period decreases)
