Calculator

A calculator with some CAS (Computer Algebra System) functionality.

Eval

Evaluate a basic equation

$ dotnet run eval '5+2*3'
11

$ dotnet run eval '~2^4'
-16

Support for basic functions and constants

$ dotnet run eval 'max(cos(pi),cos(pi/2))'
0

Support for substituting variables

$ dotnet run eval 'x^4' x=~2
-16

CAS (Computer Algebra System)

Simplify a polynomial

$ dotnet run cas 'x^2+2x^2-3x' simplify
3x^2-3x

$ dotnet run cas '(-3x+5)^4' binomialtheorem
81x^4-540x^3+1350x^2-1500x+625

Factorize a polynomial

$ dotnet run cas '3a^2+10a-1000' polyfactor a
(a+20)(3a-50)

Perform synthetic division on a polynomial

$ dotnet run cas 'x^2-5x+6' syntheticdiv 2 x
x-3 | remainder: 0

Use shoelace formula to calculate area of polygon given vertices

$ dotnet run cas (1,6)(3,-1)(-5,-3)(-4,3) shoelace
43.5

and more to come! (hopefully)
