Calculus Skill

LiveStart here

Pricing, risk and machine learning all rest on a few calculus ideas: how a quantity changes (derivatives), how changes add up (integrals), and how to approximate and optimise. This skill teaches them with finance examples and short checks: numbers you compute, formulas you type, matrices you fill in. It ends with a code lab that computes the Greeks of an option two ways, by finite differences and by formula, and compares them.
