Trigonometry Functions
RPNCalc does not consider itself a fully fledged scientific calculator (at least not currently). However, it's certainly beyond a very basic calculator. The trigonometry commands listed here are basic, but do fill a need if you need to do a few basic calculations.
Lastly, I'm happy to add more capabilities if there is a desire (and an offer to help test).
Command | Description |
|---|---|
| sin [rad] cos [rad] tan [rad] | Calculate the trigonometry function requested. Angles are input as degrees by default unless the optional rad parameter is given in which case the angles will be in radians.Example: tan will calculate the tangent using line1 as the angle in degrees. Use tan rad if line1 contains the angle in radians |
| asin [rad] acos [rad] atan [rad] | Calculate the arc trigonometry function. Like the above, the result is returned in degrees unless rad parameter is provided |
| hypot hypotenuse | Assumes the top two stack items are the right triangle' legs and this function returns the hypotenuse using the Pythagorean theorem. Specifically, it returns SQRT( (line1^2 + line2^2 )). The hypotenuse will replace the values of the two legs on the stack |
