The Tangent Function (VCE SSCE Mathematical Methods): Flashcards

$\tan \theta = \frac{\sin \theta}{\cos \theta}$

$\pi$ units

All real numbers ($\mathbb{R}$)

$\theta = \frac{(2k+1)\pi}{2}$ (odd multiples of $\frac{\pi}{2}$)

$\theta = k\pi$ (integer multiples of $\pi$)

$\frac{\pi}{n}$

$1$

$\sqrt{3}$

$\tan(-\theta) = -\tan \theta$

Convert to $\tan(nx) = k$
