Learn differential equations for free—differential equations, separable equations, exact equations, integrating factors, and homogeneous equations, and more.

The equations in examples (c) and (d) are called partial di erential equations (PDE), since y'+\frac {4} {x}y=x^3y^2. y'+\frac {4} {x}y=x^3y^2, y (2)=-1. laplace\:y^ {\prime}+2y=12\sin (2t),y (0)=5. bernoulli\:\frac {dr} {dθ}=\frac {r^2} {θ} ordinary-differential-equation-calculator. en.

The intro section to the web book, Yap, Visualizing and Utilizing Symmetries of Differential Equations, has some nice animations scaling a homogeneous ODE. Now we come to ideas that go beyond a typical first course in ODEs in the US.
In mathematics, an ordinary differential equation (ODE) is a differential equation containing one or more functions of one independent variable and the derivatives of those functions.
