Tangent

This article page is a stub, please help by expanding it.

The tangent of an angle $\scriptstyle \theta \,$, denoted as $\scriptstyle \tan \theta \,$, is one of the most important [circular] trigonometric functions.

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

(see sine and cosine).

For the decimal expansion of the tangent of 1 to 59 degrees, see A019899 through A019957 (the A-number is given by 19898 plus the desired number of degrees from 1 to 59).
