expand
Expands an expression algebraically.
expand distributes products over sums, expands supported integer powers, and recursively expands algebraic structure. It is useful when a multiplied or powered form needs to be rewritten as an explicit sum of terms.
Expansion does not mean numerical evaluation; symbols and supported functions remain symbolic.
Examples
These examples use Nerdamer Notation.
Expand a binomial power exactly.
expand((x+1)^3)
// → 1+3*x+3*x^2+x^3Distribute a symbolic product and collect the result.
expand((x+y)*(x-y))
// → x^2-y^2Interfaces
The same operation is available through the interfaces below.
Nerdamer Notation
Use this form inside input passed to nerdamer(...).
expand(arg1)nerdamer.expand
Call the operation through the default nerdamer import.
