How to memorize the families that are $\sin$, $\cos$, and $\tan$ of $\pi$ over something? Is there any way to easily memorize these? Such as $\sin \frac{\pi}{6} = 1/2$. Any help needed!!!

Here's a nice trick:
$$
\sin\left(0\right) = \sqrt{\frac{0}{4}}\\
\sin\left(\frac{\pi}{6}\right) = \sqrt{\frac{1}{4}}\\
\sin\left(\frac{\pi}{4}\right) = \sqrt{\frac{2}{4}}\\
\sin\left(\frac{\pi}{3}\right) = \sqrt{\frac{3}{4}}\\
\sin\left(\frac{\pi}{2}\right) = \sqrt{\frac{4}{4}}
$$
where the angles are in increasing order.
