What is the difference between partial differentials and ordinary differentials?

The difference between partial differentials and ordinary differentials.
Explanation of Solution
In ordinary differentials, the total derivative of the function is depends on a single variable alone.
For example:
Consider the function
The total derivative of function
In partial differentials, the total derivative of the function is depends on two variables.
For example:
Consider the function
The total derivative of function
Here, the function
