I understand how to manually approximate sine and cosine, but I can't find the formula for tangent anywhere. What about inverse trigonometric functions?

How would I apply that to find the tangent?

Just find the Maclaurin series doofus. And you didn't look very hard.

They exist, but they require the bernoulli numbers or other non-elementary number sequences.

For tangent:
$\sum\limits_{n=-\infty}^{\infty}{1 \over \pi(n+1/2)-x}$
For inverses just use the integral definition and taylor expand the integrand.
