BQN has a system value <code>•math</code> which contains trigonometry functions. Inputs are given in radians. These functions can also be used with BQN's Inverse modifier (<code>⁼</code>) to get their respective defined inverses. |
|||
Some results may be inaccurate due to floating point issues. |

The following is done in the BQN REPL: |
