Rychu 

Easy to use library for computing math formulas, mean and proportion. Is a basis of Rychusoft.NumericalLibraries. var calc = new Calculator("8^2+5-cos(2*PI)"); var result = calc.Compute(); // result = 68"

Easy to use library for validating Polish NIP numbers: string nip = "8674068337"; bool isValid = Rychusoft.Validators.NipValidator.IsValid(nip);

Easy to use library for validating Polish PESEL numbers: string pesel = "44051401458"; bool isValid = Rychusoft.Validators.PeselValidator.IsValid(pesel);

Easy to use library for computing derivative and function value at given point. var derivative = new Derivative("x^2 + 5 - cos(2 * PI * x)"); var result = derivative.ComputeDerivative(1); // result = 2
