Exercise · ZW-DIFFERENTIAL-EQUATION-001 · ★☆☆ Basic
Which of the following is a differential equation?
Choose one option.
Show answer
- A. \(y'=3y\)
Explanation
Only \(y'=3y\) relates a function to its derivative; the others contain no derivatives.
Review the concept: Differential equation
A differential equation is an equation \(F=0\) whose unknown is a function \(y\) and which relates it to one or more of its derivatives.
\[F\left(x,\,y,\,y',\,\dots,\,y^{(n)}\right)=0\]
