Hace 3 días · A Bessel equation is a special case of a confluent hypergeometric equation. The Bessel function of the first kind of order ν: where Γ(z) = ∫∞0xz − 1e − xdx is the gamma function. There are two Bessel functions of the second kind of order ν: one is called the Weber function: Yν(x) = cosνπJν(x) − J − ν(x) sinνπ.
