What is a Partial Differentiation Calculator?

In Calculus, partial derivatives are the functions having more than one variable in the function, but we differentiate the whole function with respect to one of these variables. This process of calculation is a mind confusing for students due to which we offer this free calculator. The partial derivatives calculator provides the step by step and accurate solution of any type of problem related to partial differentiation.

The partial differentiation calculator is very easy to operate. You can use it right on your device. A partial derivative calculator is a tool for calculating an ordinary derivative function of a variable with a fixed value of the other variable.

The multivariable derivative calculator is an online calculator that is used to find the derivative of different variables. The calculator is free to use have no charges and the user can use it independently and can solve as many problems as he/she can. You can also try our dy dx calculator to find derivatives of implicitly defined functions.

Formula Used by Partial Derivative Calculator with Steps

Parial derivative of any function f(x,y) depends upon the two different variables "x" and "y" at the same time. But for the calculation of partial differentiation of a function, we differentiate the whole function with respect to one of these variables.

Following is the formula used in calculator to get the partial derivative of function f(x,y) w.r.t "x":

$$ \frac{∂f}{∂x} = \frac{∂f}{∂u}\frac{∂u}{∂x} \;+\; \frac{∂f}{∂v}\frac{∂v}{∂x} $$

Similarly, partial derivative of a function, w.r.t "y" is:

$$ \frac{∂f}{∂y} = \frac{∂f}{∂u}\frac{∂u}{∂y} \;+\; \frac{∂f}{∂v}\frac{∂v}{∂y} $$

Let's see how to calculate partial derivative with an example:

Example: Integrate the following function w.r.t "x"

$$ u(x,y) \;=\; \int xy dx \;+\; f(y) $$

where,

f(y)= any differentiable function of y

$$ u(x,y) \;=\; \frac{x^2}{2} \;+\; f(y) $$

By using u(0,y) = 3y

$$ 3y \;=\; u(0,y) \;=\; \frac{x^2}{2} \;+\; f(y) $$ $$ f(y) \;=\; 3y $$ $$ u(x,y) \;=\; \frac{x^2}{2} \;+\; 3y $$

So in the same way, our calculator solve for partial derivatives of the function with detailed solution.

Frequently Asked Question

Find the First Partial Derivatives of the Function. f(x, y) = ax + by cx + dy

The first partial derivatives of the given function: f(x,y) = ax + by, cx + dy, is

For function: f(x,y) = ax + by,

$$ With\; respect\; to\; x\;: \frac{\partial f}{\partial x} \;=\; a $$

$$ With\; respect\; to\; y\;: \frac{\partial f}{\partial y} \;=\; b $$

For the function f(x,y) = cx + dy,

$$ With\; respect\; to\; x\;: \frac{\partial f}{\partial x} \;=\; c $$

$$ With\; respect\; to\; y\;: \frac{\partial f}{\partial y} \;=\; d $$

The two variable derivative calculator determines each derivative easily as well.

Find the First Partial Derivatives of the Function. z = x sin(xy)

With respect to x:

$$ \frac{\partial z}{\partial x} \;=\; \frac{\partial }{\partial x} \biggr(x sin(xy) \biggr) $$

Using product rule,

$$ 1 . sin(xy) + x. \frac{\partial }{\partial x} \biggr(sin(xy) \biggr) $$

Differentiating sin(xy):

$$ \;=\; sin(xy) + x . cos(xy) . y $$

So,

$$ \frac{\partial z}{\partial x} \;=\; sin(xy) + x cos(xy) y $$

With respect to y:

$$ \frac{\partial z}{\partial y} \;=\; \frac{\partial }{\partial y} \biggr( x sin(xy) \biggr) $$

Using the product rule,

$$ \;=\; x . cos(xy) . x $$

So,

$$ \frac{\partial z}{\partial y} \;=\; x^2 cos(xy) $$

Therefore,

$$ \frac{\partial z}{\partial x} \;=\; sin(xy) + x cos(xy) y $$

$$ \frac{\partial z}{\partial y} \;=\; x^2 cos(xy) $$

Find the First Partial Derivatives of the Function. f(x, t) = x ln(t)

With respect to x:

$$ \frac{\partial f}{\partial x} \;=\; \frac{\partial }{\partial x} \biggr( x ln(t) \biggr) $$

Using the product rule,

$$ 1. ln(t) + x. \frac{\partial }{\partial x} \biggr(ln (t) \biggr) $$

Differentiating ln(t),

$$ \;=\; ln(t) $$

With respect to t:

$$ \frac{\partial f}{\partial t} \;=\; \frac{\partial }{\partial t} \biggr(x ln(t) \biggr) $$

Using the product rule,

$$ \;=\; x . \frac{1}{t} $$

Therefore,

$$ \frac{\partial f}{\partial x} \;=\; ln(t) $$

$$ \frac{\partial f}{\partial t} \;=\; \frac{x}{t} $$

How to Estimate Partial Derivatives from Contour Maps

To estimate the partial derivatives from contour maps, follow some simple steps:

Choose the variable and pick two nearby contour lines.
Now find how much the value of the function changes in these contour lines.
Determine the distance between these contour lines.
Now divide the change in function value by the distance and you will get the answer.

How to Take Partial Derivative

Taking the partial derivative means finding the rate at which the function changes with respect to the given variable. For taking the partial derivative:

Identify the function and choose the variable
Take other variables as constant and simplify the result.
