Lagrange, divided differences, splines, error bounds

## Why it matters

The theory of computing accurate approximate solutions; bridges continuous mathematics to the digital computer.

## Where it is used

Scientific computing, simulation, ML training loops, engineering analysis, financial pricing models.

## How you know you have learned it

Produce working code/model + convergence/validation/error analysis.

## What you need first
