A formal/symbolic calculator is an computation program that allows all calculations (with or without unknown) and answer an exact result (or approximate) with the most simplification possible.

It can also be used to perform classic numerical calculations.

Write the calculation to be performed (if there are variables or functions, respect the syntax).

__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.

Most common functions (parenthesis are mandatory) are

sqrt() or √() | square root |
---|---|

exp() | exponential |

log() or ln() | natural logarithm (base e) |

log2() | logarithm (base 2) |

log10() | logarithm (base 10) |

cos() | cosine |

sin() | sine |

tan() or tg() | tangent |

arcsin() or asin() | arc sine |

arccos() or acos() | arc cosine |

arctan() or atan() | arc tangent |

csc() | cosecant |

sec() | secant |

cot() | cotangent |

arccsc() or ascs() | arc cosecant |

arcsec() or asec() | arc secant |

arccot() or acot() | arc-cotangent |

cosh() | hyperbolic cosine |

sinh() | hyperbolic sine |

tanh() or tgh() | hyperbolic tangent |

arcsinh() or asinh() | hyperbolic arc sine |

arccosh() or acosh() | hyperbolic arc cosine |

arctanh() or atanh() | hyperbolic arc tangent |

csch() | hyperbolic cosecant |

sech() | hyperbolic secant |

coth() | hyperbolic cotangent |

arccsch() or ascsh() | hyperbolic arc cosecant |

arcsech() or asech() | hyperbolic arc secant |

arccoth() or acoth() | hyperbolic arc cotangent |

abs() | absolute value |

sign() | function sign |

arg() | argument |

im() | imaginary part |

re() | real part |

ii (double i) | i (imaginary unit) |

A formal calculator can perform symbolic calculations, while a standard calculator performs numerical calculations. The formal calculator preserves variables and symbolic expressions.
