What is the Laplacian?

Laplacian is defined as the divergence of a gradient of a scalar function. Its operator is represented ∇2f as a laplacian operator. If f( x, y, z) is a continuous and differentiated function, then the Laplacian equation of f( x, y, z) is the divergence of the gradient in 3-D.

The gradient gives the rate of change in a particular direction whereas the divergence is the flow in or out of a tiny sphere around that point used in the Laplacian equation.

The Laplacian operator finds widespread application in various fields, including physics, engineering, and image processing. Further, if you would like to explore the transformative power of the Laplacian operator and its applications in various domains. you can use our fourier transform graph calculator, which complements the study of Laplacian operators by providing insights into frequency domain analysis and signal processing.

Formula Behind Laplacian Operator Calculator

Laplacian formula depends on the gradient and divergence function to solve complex differential equations. Laplacian formula can change according to given differential equations like for cartesian, cylindrical, and spherical forms as given below.

The formula on which the Laplacian calculator with steps solves the Laplacian problems is given below,


$$ \nabla^2 \;=\; \frac{\partial^2}{\partial x^2} + \frac{\partial^2}{\partial y^2} + \frac{\partial^2}{\partial z^2} $$


$$ \nabla^2 \;=\; \frac{\partial^2}{\partial r^2} + \frac{1}{r} \frac{\partial }{\partial r} + \frac{1}{r^2} \frac{\partial^2}{\partial \varnothing^2} + \frac{\partial^2}{\partial z^2} $$


$$ \nabla^2 \;=\; \frac{1}{r^2} \frac{\partial }{\partial r} \biggr( r^2 \frac{\partial }{\partial r} \biggr) + \frac{1}{r^2 sin \emptyset} \frac{\partial}{\partial \emptyset} \biggr( sin \emptyset \frac{\partial}{\partial \emptyset} \biggr) + \frac{1}{r^2 sin^2 \emptyset} \frac{\partial^2}{\partial \varnothing^2} $$

Working of Laplacian in Spherical Coordinates Calculator

The Laplacian operator mask calculator uses the simplest method to calculate the complicated different equations whether it is present in parametric or algebraic equations. Resultantly it gives you precise solutions according to your given input so that you can easily understand this Laplacian concept.

When you give the different equations as input in our Laplacian vector calculator, it will analyze whether the differential equation is parametric or algebraic. After identifying, it applies the Laplacian formula to find the divergence.

You can solve three different types of systems (cylindrical, spherical, and cartesian equations) using the Laplacian calculator for three dimensions. Let's discuss these cases one by one to check the working process.

  • For Cartesian

If the differential equation is in cartesian form then it simply takes the gradient of f(x,y,z) and gives the solution.

  • For Cylindrical

If the given input function is in cylindrical form(r,φ,z) then the calculator does some extra calculations along with divergence. For it first finds out the radius of a function if it is not given from

$$ r \;=\; \sqrt{x^2 + y^2 + z^2} $$

then it applies a cylindrical Laplacian form to give you an accurate solution.

  • For Spherical

If the given input function is in spherical form (θ,r,φ) then the laplacian of a vector calculator first finds the sinθ and r 2= x2 + y2 + z2 then add these values in the spherical Laplacian formula. It will give the solution of the spherical Laplacian equation immediately.

For more calculations related to transformations, such as the Z Transform, you can also use our z transformation of functions calculator to simplify your computations further. The Z Transform Calculator allows you to convert discrete-time signals from the time domain to the frequency domain, facilitating analysis in areas like signal processing, control systems, and more.

Let us discuss an example with the solution of the Laplacian function to observe the Laplacian in spherical coordinates calculator working process for better understanding.

Example of Laplacian Problem:

The solution of the Laplacian problem is given below to let to understand the manual calculation. Although the Laplacian calculator with steps is here to help you but it is also important to know the manual calculations.


Calculate ▽f using the Laplacian method.


Now we have to evaluate ▽f, so:

$$ \nabla^2 f \;=\; \frac{\partial^2 f}{\partial x^2} + \frac{\partial^2 f}{\partial y^2} + \frac{\partial^2 f}{\partial z^2} $$

As we know:

$$ f \;=\; 3x^3 y^2 z^3 $$

Putting the value in the equation:

$$ \frac{\partial^2 f}{\partial x^2} (3x^3 y^2 z^3) + \frac{\partial^2 f}{\partial y^2} (3x^3 y^2 z^3) + \frac{\partial^2}{\partial z^2} (3x^3 y^2 z^3) $$

$$ \frac{\partial }{\partial x}(9x^2 y^2 z^3) + \frac{\partial }{\partial y}(6x^3 yz^3) + \frac{\partial }{\partial z}(9x^3 y^2 z^2) $$

$$ 18xy^2 z^3 + 6x^3z^3 + 18x^3 y^2 z $$

Extracting the common factors,

$$ \nabla^2 f \;=\; 6xz \biggr( 3y^2 z^2 + x^2 z^2 + 3x^2 y^2 \biggr) $$

$$ 6xz \biggr( 3y^2 (z^2 + x^2) + x^2 z^2 \biggr) $$

Thus it is the final solution of our function with specific limits. Solve this example further, you can apply the inverse Laplace transform. This will convert the given expression from the Laplace domain back to the time domain. You can use our laplace transform inverse calculator to perform this conversion efficiently.
