Abstract
Integral representations of the Kelvin functions ber v x and bei v x and their derivatives with respect to the order are considered. Using the Laplace transform technique the derivatives are expressed in terms of finite integrals. The Kelvin functions ber n+1/2 x and bei n+1/2 x can be presented in a closed form.
