Physics I / Differential models in one variable
Practice question · Fill in the blanks

Complete the description of a separable first-order ODE.

A separable ODE has the form dy/dx = ______. We solve it by bringing y-terms to one side: (1/h(y)h(y)) dy=g(x)dy = g(x) dx, then integrating ______ sides independently.

Word bank: g(x)h(y)g(x) \cdot h(y) · both · neither · f(x+y)f(x+y)

Hints
  1. Separable means each variable can be gathered onto its own side.
  2. The step that follows separation is integrating both sides.
Show the answer

A separable ODE has the form dy/dx = g(x)h(y)g(x) \cdot h(y). We solve it by bringing y-terms to one side: (1/h(y)h(y)) dy=g(x)dy = g(x) dx, then integrating both sides independently.

Why

Separation works because variables can be moved independently to each side.
