Differential Calculus Applications
Differentiation and its applications — limits, continuity, derivative rules, tangents/normals, monotonicity, maxima/minima and Mean Value Theorems — are heavily tested in the IAT. Speed comes from having standard derivatives and the chain/product/quotient rules automatic, then translating word problems into optimisation or rate-of-change setups.
