By chain rule,

After this I am struck.
Partial differentiation is a mathematical concept used to find the rate of change of a function with respect to one of its variables, while holding all other variables constant. It is commonly used in multi-variable calculus to analyze the behavior of functions with more than one independent variable.
Ordinary differentiation involves finding the rate of change of a function with respect to a single independent variable. Partial differentiation, on the other hand, involves finding the rate of change with respect to one variable while keeping all other variables constant.
The purpose of partial differentiation is to help us understand how a function behaves when more than one variable is involved. It also allows us to find the maximum and minimum values of a function with multiple variables, which is useful in optimization problems.
Partial differentiation has many real-world applications, such as in economics, physics, and engineering. For example, in economics, partial differentiation can be used to analyze the relationship between two or more variables, such as demand and price, in order to make informed decisions about production and pricing strategies.
To find a partial derivative, we treat all other variables as constants and differentiate the function with respect to the variable of interest. This process is repeated for each variable in the function, resulting in a set of partial derivatives. These derivatives can then be used to analyze the behavior of the function and solve for critical points.
