Differential Equations: Modeling Change
Turn rules about rates of change into precise predictions of the future. Learn to read slope fields, solve foundational equations, and visualize dynamic systems in motion.
Like Duolingo, but for Differential Equations: Modeling Change. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
A short one: 12 levels across 2 sections, about 24 minutes end to end, roughly 5 days at five minutes a day. It moves through Mapping and Solving First-Order Rates and Tracking Systems and Oscillations. It starts from scratch.

Key ideas in Differential Equations: Modeling Change
- Plugging coordinates into dy/dx outputs the slope of the curve at that point, not the height or location of the curve
- A differential equation acts like a local speed-and-direction guide across the coordinate plane
- The value of dy/dx gives the steepness and direction of a tiny tangent line drawn at (x, y)
- A slope field consists of short tangent line segments plotted across a coordinate grid
- Tracing a curve means letting the local segment angles steer your pencil continuously like currents in water
- A curve must stay tangent to the segments it passes through rather than crossing them at sharp angles
- A differential equation produces an entire family of curves because different starting heights share the same slope pattern
- Specifying a single coordinate pair (an initial condition like y(0) = 3) anchors your pencil to one unique trajectory
- Different initial points never cross each other in a standard smooth slope field
- Equilibrium occurs where the rate of change dy/dx equals zero
- A slope of zero renders as completely flat horizontal line segments across a specific y-level
- A trajectory starting on a flat equilibrium line stays flat forever because the rate of change is zero
- Curves funnel toward an equilibrium line when slopes push toward it from both sides
- You can predict where y goes as x grows large simply by following the directional arrows without solving the equation algebraically
- When surrounding slopes push toward a constant line, that line acts as a stable attractor
- Separation of variables requires collecting all y terms with dy on one side and all x terms with dx on the other
