A foundational idea in Mathematica is that all expressions—whatever they may represent—ultimately have a uniform tree-like structure.

MaxExtraConditions is an option to Solve and related functions that specifies how many extra equational conditions on continuous parameters to allow in solutions that are ...

Mathematica's symbolic character allows a powerful unification of the notion of conditionals in programming and in mathematics.

Sec[z] gives the secant of z.

When building an initial statistical model, you may not have a good idea of what parametric distribution family it should come from. Nonparametric distributions make very few ...

ArcCosh[z] gives the inverse hyperbolic cosine cosh -1 (z) of the complex number z.

You can think of an expression like f[x] as being formed by applying an operator f to the expression x. You can think of an expression like f[g[x]] as the result of composing ...
