Defining Functions. There are many functions that are built into the Wolfram Language. This tutorial discusses how you can add your own simple functions to the Wolfram Language. As a first example, consider adding a function called f which squares its argument. The Wolfram Language command to define this function is f [ x_] :=x^2.
In the Wolfram Language a variable can not only stand for a value, but can also be used purely symbolically. And building on the Wolfram Language's powerful pattern language, "functions" can be defined not just to take arguments, but to transform a pattern with any structure. x = … — set a variable. f [ x _]:= … — define a function that ...
Define a function of two arguments named x and y: Copy to clipboard. In [1]:=. 1. . f [x_, y_] := x + y. Notes for Java programmers: In basic Wolfram Language function definitions, parameter names are followed by _ ("blank"). Unlike Java methods, Wolfram Language functions will accept any type of data by default.
Special functions refer to mathematical functions having particular usage in the study of analysis, physics, or another branch of science or mathematics.
In mathematics, a function is defined as a relation, numerical or symbolic, between a set of inputs (known as the function's domain) and a set of potential ...
Use interactive calculators to plot and graph functions. Try 3D plots, equations, inequalities, polar and parametric plots. Specify ranges for variables.
40. Defining Your Own Functions. As we ’ ve seen in this book, there ’ s a huge amount that can be done with functions that are already built into the Wolfram Language. But you can go even further if you define your own functions too. And the Wolfram Language has a …
Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals. For math, science, nutrition, ...
Every Wolfram Language symbol exists in a 'context'. Built-in symbols are in the System` context, and by default, user-defined symbols are in the Global` context. When a new session is started, the Global` context is normally empty:When you create a symbol, it is added to the Global` context:When you define a function, the function name is added to the Global` context along …
As a first example, consider adding a function called f which squares its argument. The Wolfram Language command to define this function is f[x_]:=x^2.
The domain of a function describes the set of numbers on which the function can act. Its range, or image, is the set of values the function can return. Wolfram| ...
Wolfram language allows one to define a pure function in which arguments are specified as #, #1, #2, etc. There are several equivalent ways to write pure ...
Alpha is pretty bad about doing anything to a piecewise defined function. Dervatives don't seem to want to work. However, you can coax Alpha to do this by using ...
In mathematics, a function is defined as a relation, numerical or symbolic, between a set of inputs (known as the function's domain) and a set of potential outputs (the function's codomain). The power of the Wolfram Language enables Wolfram|Alpha to compute properties both for generic functional forms input by the user and for hundreds of known ...
The symbolic language paradigm of the Wolfram Language takes the concept of variables and functions to a new level. In the Wolfram Language a variable can not only stand for a value, but can also be used purely symbolically. And building on the Wolfram Language's powerful pattern language, "functions" can be defined not just to take arguments, but to transform a pattern with …
Every Wolfram Language symbol exists in a “ context ”. Built-in symbols are in the System` context, and by default, user-defined symbols are in the Global` context. When a new session is started, the Global` context is normally empty: Out [1]=. 1.
In mathematics, a function is defined as a relation, numerical or symbolic, between a set of inputs (known as the function's domain) and a set of potential outputs (the function's codomain). The power of the Wolfram Language enables Wolfram|Alpha to compute properties both for generic functional forms input by the user and for hundreds of known special functions.

As a first example, consider adding a function called f which squares its argument. The Wolfram Language command to define this function is f[x_]:=x^2. The _ (referred to as "blank") on the left-hand side is very important; …
23.02.2011 · You can specify boundaries of the function parameters in Wolfram Alpha. They are more of a hint to the plotting library how much to scale the plot than exact boundaries, so in your case y is not calculated only with a value of 3.
