About Differential Equations

Differential equations describe relationships involving derivatives – the rates of change of one variable with respect to another. They are fundamental in modeling physical, biological, and economic systems.

Example Formulas Solved by This Calculator:

First-Order ODE:  dy/dx = x + y

Second-Order ODE:  d²y/dx² + 4dy/dx + 4y = 0

System of ODEs:   dx/dt = y, dy/dt = -x
