Question

Ordinary differential equation definition

Answer 1

ordinary differential equations is called that those make differential equations of equations

Answer 2

Answer:

Ordinary differential equation is an equation which involves one independent variable.

For example,

$\Large \sf \frac{d^2x}{dy^2} + y + 4 = 0$

Here in the above example you can clearly see there is one independent variable that is y

How y ?

It's because you can see in $\Large \sf \frac{d^2x}{dy^2}$ that x is dependent on y that means y is independent
