A conceptual, intuition-first introduction to calculus for readers who remember the idea of “slope at a point” but never truly understood what it meant.
Many people take calculus and walk away remembering almost nothing—except a vague idea about slopes, curves, and something called a tangent.
Thinking in Calculus is written for those readers.
Rather than teaching calculus as a collection of formulas and procedures, this book treats it as a way of thinking about how quantities change, accumulate, and move. Concepts like limits, derivatives, and integrals are introduced through intuition, visualization, and physical reasoning before formal notation ever takes center stage.
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—clearly, patiently, and without intimidation.
