Bessel Function Calculator

Introduction to Bessel Function Calculator:

Bessel function calculator is an advanced mathematical calculator that is used to find the differential equation of nonsingular functions and provide linearly independent solutions in fractions of a second.

Our bessel function integral calculator is very beneficial for students, engineers, or researchers because the Bessel function has different applications in scientific fields like Acoustic theory, Electric field theory, hydrodynamics, nuclear physics, radio physics, etc.

What is the Bessel Function?

Bessel function is defined as the function of a higher order differential equation that is finite at its origin at x=0.

The Bessel function becomes a Bessel equation when its first-order differential function combines with the second-order differential function. This method is mostly used in the quantum physics field.

Formula of Bessel Function:

Bessel function formula is a combination of first-order and second-order differential equations. The formula utilized by our bessel function calculator is,

$$ J_{\alpha}(x) \;=\; \sum_{m=0}^{\infty} \frac{(-1)^m}{m! \rceil(m+ \alpha + 2)} \biggr(\frac{x}{2}^{2m + \alpha} \biggr) $$

$$ Y_{\alpha}(x) \;=\; \frac{J_{\alpha}(x)cos(\alpha \pi) - J_{-a}(x)}{sin (\alpha \pi)} $$

$$ y(x) \;=\; C_1 J_{\alpha}(x) + C_2 Y_{\alpha}(x) $$

Whereas,

For first-order differential equations,

• J𝛼(x): First kind of Bessel function
• 𝛼: Order of the Bessel function that must be in real number
• x: Arbitrary real or complex number
• Γ(z): Gamma function

For the second-order differential equation

• Y𝛼(x): Second kind of order 𝛂 in Bessel function
• m: is an integer element of order 𝛂 in Bessel function
• Y𝛼(x): the limit of as the order 𝛂 approaches the integer n

Working Process of Bessel Function Integral Calculator:

Bessel function calculator has the simplest working process that enables you to easily understand the higher-order differential equation solution without any trouble. Our tool has an advanced algorithm that allows you to calculate various types of bessel problems.

When bessel function zeros calculator takes the input value of the differential equation, then it identifies the given equation's nature first, and then it starts the calculating process. After identification, it puts all the given data into the Bessel equation formula so that you get the solution of the Bessel equation for differential functions.

You should take the order of the Bessel function by using the bessel function of the first kind calculator in real number but the value of x can either be real or imaginary. Let's take an example of the Bessel function along with its solution to understand it better.

Solved Example of the Bessel Function:

An example of a Bessel function with solution to know its step by step calculation is given as the bessel function calculator can only help you to solve and you would know the whole process by solving it manually.

Example:

With respect to order v, bessel function is given by,

$$ x^2 y’’ + xy’+ (x^2 v^2)y \;=\; 0 $$

Solution

We will solve it by Frobenius method as x = 0,

$$ \lambda^2 - v^2 \;=\; 0 $$

Substitute the power series,

$$ y \;=\; x^v \sum_n a_n x^n $$

From bessel’s equation, we got

$$ \sum_n (n + v)(n + v-1)a_v x^{m+v} + \sum_n (n+v)a_v x^{m+v} + \sum_n (x^2 - v^2)a_v \;=\; 0 $$

$$ \biggr[(m+v)^2 - v^2 \biggr]a_m \;=\; -a_{m-2} $$

Or

$$ a_m \;=\; -\frac{1}{m(m+2v)}a_{m-2} $$

Take v = n＞0

$$ a_m \;=\; -\frac{1}{m(m+2n)}a_{m-2} $$

We will use iteration to solve it,

$$ a_{2k} \;=\; -\frac{1}{4} \frac{1}{k(k+n)}a_{2(k-1)} $$

$$ \biggr(\frac{1}{4} \biggr)^2 \frac{1}{k(k-1)(k+n)(k+n-1)} a_{2(k-2)} $$

$$ \biggr( -\frac{1}{4} \biggr)^k \frac{n!}{k!(k+n)!} a_0 $$

Choosing 1/n!2ⁿ can give,

$$ J_n(x) \;=\; \sum_{k=0}^{\infty} \frac{(-1)^k}{k!(k+n)!} \biggr(\frac{x}{2} \biggr)^{2k+n} $$
