Function value table
Sample an expression at evenly spaced X positions and export the full table.
A clear answer. Here’s how.
Evaluates a restricted expression at N evenly spaced positions including both supplied endpoints. Reversed or equal ranges are allowed and retain their requested order. Every sampled value must be finite; undefined positions cause a clear error. Samples do not prove continuity or capture every narrow feature. Exports plain numeric X and f(X) values as CSV.
