In general, differentiation of hypergeometric functions ${}_p F_q$ with respect to their numerator or denominator parameters requires the use of more complicated functions like the multivariate Kampé de Fériet function, or else do not yet have known closed forms.

WebJul 12, 2024 · The Bessel function solutions describe the radial part of the solution and one does not expect a singular solution at the center of the drum. The amplitude of the oscillation must remain finite. Thus, only Bessel functions of the first kind can be used. WebBESSELI (X, N) The BESSELI function syntax has the following arguments: X Required. The value at which to evaluate the function. N Required. The order of the Bessel function. If n is not an integer, it is truncated. Remarks If x is nonnumeric, BESSELI returns the #VALUE! error value. If n is nonnumeric, BESSELI returns the #VALUE! error value. check if string is null or empty https://thebrummiephotographer.com
