Partial Derivative Calculator

An online Partial derivative calculator is used to differentiate mathematical functions that contain multiple variables. Yes, this multivariable derivative calculator can differentiate a certain function multiple times.

What Is a Partial Derivative?

The partial derivative is defined as the derivative of a multivariable function with respect to one variable, while all other variables remain unchanged.

When a function has two variables x and y that are independent of each other, then what to do there! Simply,

• If you require differentiating the function with respect to “x”, then you should keep the variable “y” constant and differentiate.
• On the other hand, if you need to differentiate the function with respect to “y”, then make the variable “x” constant. The symbol “∂” is generally used to indicate chain rule partial derivatives

How to do a Partial Derivative of Function?

You can do these derivation calculations of a function manually by stick to these steps:

Take a function to compute the partial derivative
The derivative of a constant is zero
When applying a derivative to a variable, only the derivative of that particular variable is solved
Solve all the functions for getting the results

Second Partial Derivatives:

The high-order derivative is very important for testing the concavity of the function and confirming whether the endpoint of the function is maximum or minimum. Since the function f (x, y) is continuously differentiable in the open region, you can obtain the following set of partial second-order derivatives:

• F_{xx} = ∂fx / ∂x, where function f (x) is the first partial derivative of x.
• F_{yy} = ∂fy / ∂y, where function f (y) is the first order derivative with respect to y.

How Does Partial Derivative Calculator Work?

Our multivariable derivative calculator differentiates the given functions by following these steps:
