This library uses numerical calculator library to compute derivatives so can handle same functions.Mathematical formulas used to compute derivatives are transformations of Taylor's theorem. Both formulas are accurate to O(h^4) where h is the step used in computation (default 0.001).

### Usage

string formula = "x^3-cos(x)+3*x-sqrt(2)";

double point = 2.2;

Derivative derivative = new Derivative(formula);

double resultFirstDerivative = derivative.ComputeDerivative(point);

double resultSecondDerivative = derivative.ComputeDerivativeBis(point);

double resultFunctionValue = derivative.ComputeFunctionAtPoint(point);
