A scalar function is a function of one or more variables whose range is one-dimensional, as compared to a vector function, whose range is three-dimensional (or, in general, n-dimensional).
read moreThe term wave function is often associated explicitly with Quantum Physics, but this is just one special case of a wave function. In broader terms, a wave function is a function that satisfies a wave equation and describes the properties of a…
read moreA differential equation is an equation that imposes relations between the various derivatives of a multivariable function. It relates the rate of change of one variable in the function to the rates of change of other variables in the function.
read moreA multivariable function is just a function whose input and/or output includes multiple variables. In contrast, a function with single-number inputs and a single-number outputs is called a single-variable function.
read moreA single-variable function is a function that contains only one variable.
read moreA partial derivative of a function of several variables is its derivative with respect to one of those variables, with the others held constant. This is in contrast to the Total Derivative, in which all variables are allowed to vary. Related
read moreA variable is a symbol placeholder for a quantity that may change, or any mathematical object. Variables often represent a number, vector, matrix, function, argument, set, or element. If a variable does not actually vary, it is called a constant variable, or…
