F a;b ,b ;c; x, y гипергеометрик функцияси ва Кампе де Фериетнинг F44;3;4,3,4 [x, y] функцияси орасидаги янги муносабат олинган. Бунда Аппелнинг гипергеометрик функциясининг қаторга ёйилмасидан ҳамда текис яқинлашувчи даражали қаторларнинг ҳадларини группалаш усулидан фойдаланилган. Олинган муносабатдан Гаусс функциялари, умумлашган гипергеометрик 8 F7(x4) функция ва гиперболик косинуслар ўртасидаги боғланишлар мавжудлиги аниқланган.

In this paper, we get a new relationship between Appel’s hypergeometric function F1 (a;b1,b2;c; x, y) and Campe de Feriet’s function 4;4,4 [ ]
4;3,3
F x, y . We use expansion of series Appel's hypergeometric function and the method of grouping terms of smooth convergent power series. We find connections between Gaussian functions, generalized hypergeometric function 4
8 7
F (x ) and hyperbolic cosines by using new relationship.
