dCode brings you a formal calculator which authorizes all calculations and answer an exact result (non-approximate) with the most simplification possible.

Example: $$x^2-(x-1)(x+2)+2x = x+2$$

Example: $$x+1+x-2 = 2x-1$$

dCode gives also an equation solver, derivatives, primitives, etc.

### What are allowed functions?

Function allowed (parenthesis are compulsory) are

sqrt() or √() square root exponential natural logarithm (base e) logarithm (base 2) logarithm (base 10) cosine sine tangent arc sine arc cosine arc tangent cosecant secant cotangent arc cosecant arc secant arc-cotangent hyperbolic cosine hyperbolic sine hyperbolic tangent hyperbolic arc sine hyperbolic arc cosine hyperbolic arc tangent hyperbolic cosecant hyperbolic secant hyperbolic cotangent hyperbolic arc cosecant hyperbolic arc secant hyperbolic arc cotangent absolute value function sign argument imaginary part real part i (imaginary unit)
