Purpose of use

High-precision calculation of rapidities (hyperbolic angles) in special relativity. Manipulating hyperbolic trigonometric functions.

Comment/Request

I greatly appreciate the accuracy and flexibility of this calculator. It's very nice that I can use variables and nest functions, and the functions never seem to completely "zero out" due to a failure of precision like most calculators that are available for calculating hyperbolic trig functions. Especially since I am working with special relativity, where almost every single "daily life"-scale velocity is unbelievably small compared to the speed of light, so I am usually working with fractions on the order of a few billionths or smaller.

Purpose of use

Solving problem 751 of project Euler. Google Sheets precision was not enough and I was wanted to see if I could solve the problem without using C/C++ libraries. It worked!

Comment/Request

I cant seem to find inverse trig functions, arcsin doesnt work, sin^-1() doesnt work, sin()^-1 doesnt work either…

from Keisan

In Keisan the inverse trig functions are asin(), acos() and atan().
