### How to make a formal calculation?

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

Example: Simplification of polynomials with variable: $$x^2-(x-1)(x+2)+2x = x+2$$

Example: Computation (addition, subtraction, multiplication, division) with unknowns: $$a+1+a-2 = 2a-1$$

These are calculations with variables, but not an equation resolution. dCode has also an equation solver, and other calculus tools such as derivatives, primitives, integrals, etc.

### What are allowed functions?

Function allowed (parenthesis are mandatory) by the math calculator 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)
