Welcome!
In Calculus Typed you'll find a modern presentation of Calculus that favors certain ways of working:
- We use different types for different behaviors.
- Algebraic tools have geometric explanations.
- We learn Calculus by calculating.
You can read online or download the e-book!

Features
Types
We study several types of mathematical objects: numbers, points, metrics, vectors, rulers, and boxes. Each type has its own algebraic operations and geometric interpretations.Composition explained
By decomposing functions as schematics, we gain insight into functional dependence.Unified differential laws
We present a single set of differential laws. These can be used to take derivatives, partials, metric differentials, and ruler differentials.No chain rule
Our differential laws have the chain rule baked in. As a consequence, dependence works in a natural way: we substitute.Coherent geometry
We choose geometric interpretations that build in a coherent way.Metrics and polymetrics
Polymetrics give an algebraic approach to studying the slope, bend, and warp of a graph.Measurement
By studying rulers we see how integrals generalize the familiar act of measuring.
