Bessel function K for real numbers

Online calculator for calculating the modified Bessel function Kn (z) of the second kind

Bessel function Kn (z) of the second kind


The Bessel-K function calculates the modified Bessel function Kn (z) of the second kind. The modified Bessel functions do not show an oscillating but an exponential behavior. Bessel-K (n, z) is a solution of the modified 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 Bessel-K function calculates the modified Bessel function Kn (z) of the second kind. The modified Bessel functions do not show an oscillating but an exponential behavior. Bessel-K (n, z) is a solution of the modified Bessel differential equation.

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