Bessel function J for real numbers

Calculator for calculating the Bessel function Jv (z) of the first kind

Bessel function Jv (z) of the first kind


The function Bessel-J calculates the Bessel function Jv (z) of the first kind. The Bessel-J functions show an oscillating (not an exponential) behavior. Bessel-J (n, z) is a solution of the Bessel differential equation.

This function expects real numbers as arguments. You can find Bessel functions for complex numbers here .

To perform the calculation, enter a real number and the order number. Then click on the 'Calculate' button.

The function Bessel-J calculates the Bessel function Jv (z) of the first kind. The Bessel-J functions show an oscillating (not an exponential) behavior. Bessel-J (n, z) is a solution of the Bessel differential equation.

The result is a complex number if z is negative and n is a decimal number.
