,Streckenverhältnisse. Proportionalität,Rational mechanics, the use of partial differential calculus to study natural phenomena, was begun by Euler with his study of the motion of an ideal fluid. This led him to introduce the hypergeometric equation, and later the equations of rigid body motion.确定 发表于 2025-3-22 18:22:44
