Completion requirements
Beta: the beta function is one of the two Euler integrals, defined for all complex numbers x and y of strictly positive real parts.
Derivative: The derivative of a function of a real variable measures how much the function's value (output value) changes relative to a small change in its argument (input value). Derivative calculations are a fundamental tool of infinitesimal calculus.
Equation: An equation is a mathematical equality involving one or more variables for which we will seek the value(s) making it true. For a mathematical statement to be qualified as an equation, two items must be present: one or more variables, and an equality relation.
Fractional: A fractional number is a rational number that contains an integer part, composed of one or more units, and a fractional part, which is composed of a fraction. Mixed numbers are a way of writing improper fractions.
Function: is a type of relationship f between two variables. We call this relationship a function when each value of the independent variable is associated with one and only one value of the dependent variable.
Gamma: the gamma function (denoted by the Greek letter Γ) is a complex function, also considered as a special function. It extends the factorial function to all complex numbers (except negative integers).
Integral: An integral is the result of the mathematical operation performed on a function, called integration. An integral is therefore composed of an integrand (the function to be integrated) and an operator called an integrator.
Solution: A solution to an equation is a number that makes the equality true when replacing x with that number.
