Read the equation
The function returns x⁴/8. This equals the triangular-domain integral ∫₀ˣ∫₀ᵘ uv dv du; a rectangular-domain integral of uv over [0,x]² would instead be x⁴/4. The comment’s reused x and unspecified nested bounds are ambiguous, so the exact polynomial returned by the code is the reproducible definition.

How it works
Read the definition from its right-hand expression to the quantity on the left. Its surrounding source records the intended input, state, or parameter context. Where the source leaves an operation unspecified, this page preserves that gap.
Assumptions & limits
Source recovery establishes that the expression appears in this record. Its mathematical validity, implementation behavior, and interpretation must be assessed separately. See the linked source and research notes for the checks available for this version.
