An intuitive, Python-based introduction to calculus for readers interested in real applications of the math.

Many people take a calculus course and walk away remembering almost nothing—except vague ideas about slopes, curves, and something called a tangent.

Thinking in Calculus is written for those readers, as well as anyone else with a firm grasp of algebra and trigonometry who is eager to learn the practical math underlying machine learning optimization, signals processing, planetary simulations, and other useful applications.

Rather than teaching calculus as a collection of formulas and procedures, this book uses guided Jupyter Notebooks to introduce concepts like derivatives, integrals, the Fundamental Theorem, and dynamical systems through visualizations and real-world examples.

Designed for curious self-learners, programmers, and students who want to understand what calculus is actually describing, Thinking in Calculus rebuilds the subject from the inside out— patiently and in context.
