A partial antiderivative calculator is a powerful tool that can help you solve complex mathematical problems involving partial integrals. It works by taking a function and its partial derivatives and returning the partial antiderivative of the function with respect to a specified variable. Partial antiderivative calculators can be used to solve a wide range of problems in mathematics, physics, and engineering.
How does a partial antiderivative calculator work?
Partial antiderivative calculators typically use a variety of methods to calculate partial antiderivatives. One common method is to use integration by parts. Integration by parts is a technique that can be used to integrate a product of two functions. To use integration by parts, you must first choose two functions, $u$ and $dv$. The integral is then rewritten as the difference of two integrals, one of which is the product of $u$ and the integral of $dv$, and the other of which is the product of $v$ and the integral of $du$.
Another common method used by partial antiderivative calculators is U-substitution. U-substitution is a technique that can be used to change the form of an integral. To use U-substitution, you must first choose a new variable, $u$. The integral is then rewritten in terms of $u$ and its derivative.
Partial antiderivative calculators may also use other methods, such as Taylor series expansion and partial fraction decomposition, to calculate partial antiderivatives.

How to use a partial antiderivative calculator
To use a partial antiderivative calculator, simply enter the function into the calculator and select the variable with respect to which you want to take the partial integral. The calculator will then return the partial antiderivative of the function.
Examples of how to use a partial antiderivative calculator
Here are a few examples of how to use a partial antiderivative calculator:
Example 1: Finding the partial antiderivative of a function with respect to x
Let’s say we want to find the partial antiderivative of the function $f(x, y) = xy^2$ with respect to x. To do this, we would enter the function into the calculator and select x as the variable with respect to which we want to take the partial integral. The calculator would then return the following result:
∂f/∂x = xy^2
Example 2: Finding the partial antiderivative of a function with respect to y
Let’s say we want to find the partial antiderivative of the function $f(x, y) = xy^2$ with respect to y. To do this, we would enter the function into the calculator and select y as the variable with respect to which we want to take the partial integral. The calculator would then return the following result:
∂f/∂y = 2xy
Example 3: Finding the partial antiderivative of a function with respect to multiple variables
Let’s say we want to find the partial antiderivative of the function $f(x, y, z) = xyz$ with respect to x. To do this, we would enter the function into the calculator and select x as the variable with respect to which we want to take the partial integral. The calculator would then return the following result:
∂f/∂x = yz
