Differential Equations

Learn DEs like research: observe → hypothesize → model → solve → reflect.

What is a Differential Equation?

A DE doesn’t give you a number; it gives you a rule about things change.

Slope Fields: Behavior Maps

See how solutions behave before you learn any solving techniques.

1 lessons

Growth & Decay (Separable Equations)

Build the model first, then learn the technique that matches it.

1 lessons

Integrating Factors (Why it works)

A structured way to make a messy derivative become clean.

As this expands, you’ll connect DEs to motion, energy, circuits, and real data.
