प्रश्न

Write the order of the differential equation of all non-horizontal lines in a plane.

Advertisements

उत्तर

The equation of the non - horizontal lines in a plane is
\[y = mx + c, \]
where m is the slope and c is the intercept on y - axis .
Differentiating with respect to x, we get
\[\frac{dy}{dx} = m\]
\[ \Rightarrow \frac{d^2 y}{d x^2} = 0\]
This is the required differential equation . 
Here, we observe that the order of the required differential equation is 2 .
