Mar 1, 2015 · On the assumption that you have defined the functions u[x], a[x] and b[x] elsewhere, you can define a function as follows: f[x_] := u'[x] + a[x] u[x] + b[x] However, I recommend you …

f=(# ^2&) and f[n_]:=n^2 are two ways of defining a function, that for example give the same results for f[10]. Pure function definitions tend to be easier to combine with each other, but …

4 days ago · A powerful tool of Mathematica is its ability to manipulate user-defined functions. This functions can be not only in terms of the internal build-in functions, but also in terms of …

Sep 22, 2012 · How can I define a general function without the exact expression in Mathematica? For example, I don't need this: a[x_, y_]:= 2x + 3y, I need to work with a general parameter …

Defining a function in the Wolfram Language. The names like f that you use for functions in the Wolfram Language are just symbols. Because of this, you should make sure to avoid using …

Example of defining your own function: F[x_]:= E^x Sin[a x] . The "F[x_] :=" construction allows you to call F repeatedly with different x values, just as you do for the built-in functions.

Defining Functions: Defining a new function in Mathematica is also slightly tricky, syntax-wise. Basically when defining a function you are defining an operation that can be applied to …
