IB Math AA SL Calculus - 5.4 Maximums and Minimums and Stationary Points

Here we put derivatives to work and finally answer the question: where does the graph stop going up… and start going down? In this lesson, we break down stationary points and use them to find local maximums and minimums.

You’ll see how setting the derivative equal to zero tells us when a function takes a pause, and how a quick sign check lets us decide whether it’s a peak, a valley, or just a dramatic moment that goes nowhere.

This is where calculus stops being about grinding through algebra and starts doing something useful — like finding the highest and lowest points without staring at a graph and hoping for the best.

Perfect for IB students who want their calculus clean, confident, and exam-ready.
