RE: Arctangent function program [HP-42S, Free42]
This program for HP-42S calculates \(\sin(x)\) and \(\cos(x)\) based on \(\tan(\frac{x}{2})\):
Code: 00 { 63-Byte Prgm } Hitting the [÷] button calculates \(\tan(x)\). Example 1 R/S y: 0.8414709848078965065362209309116153 x: 0.54030230586813971758203414358187 ÷ x: 1.557407724654902229769750316481308 |
