DiffeCalc | ODE Visualizer

DiffeCalc is a free online tool for visualizing ordinary differential equations. Enter any first-order ODE of the form dy/dt = f(t, y), set initial conditions, and instantly plot solution curves or direction fields.

Features

Graph solution curves for any first-order ODE using numerical integration
View vector (direction) fields to understand qualitative behavior
Plot multiple solution curves with different initial conditions
Supports common math functions: sin, cos, tan, exp, log, sqrt, abs, pow
