The solution of the differential equation \(\frac{dy}{dx}=\frac{y}{x}\) is
Q1 FREE PREVIEW
The solution of the differential equation \(\frac{dy}{dx}=\frac{y}{x}\) is
✓ Correct answer: b)
\(y=cx\)
Explanation
The given differential equation is:
\(\frac{dy}{dx}=\frac{y}{x}.....(I)\)
Rearrange the tems of the equation \(\left(I\right)\)
\(\frac{dy}{y}=\frac{dx}{x}.....(II)\)
Integrate on both sides of equation \((II)\) and calculate the solution of the given differential equation.
\(\int \frac{dy}{y}=\int \frac{dx}{x}\\ \log (y)=\log (x)+\log (c)\\ \log (y)=\log (cx)\\ y=cx\)
Hence, the solution of the given differential equation is \(y=cx\).
