This method was applied for a shallow shell in the form of right helicoid.shallow shellarbitrary coordinate systemcoefficients of the fundamen- tal forms of surfaceEuler type of the equationright helicoidпологие оболочкинесопряженная ортогональная система координаткоэффициенты квадратичных формдифференциальные уравнения типа Эй- лерапрямой геликоидбезразмерные координаты
