1、罗尔中值定理 罗尔(Rolle)定理如果函数f(x)在闭区间 a,b]上连续,在开区间(a,b)内可导,且在区间端 一点的函数值相等,即f(a)=f(b),那末在(a,b) 内至少有一点E(a<

In this lecture we will consider the equations that result from integrating Newtons second law, F=ma, in time. This will lead to the principle of linear impulse and momentum. This principle is very useful when solving problems in which we are interested in determining the global effect of a force acting on a particle over a time interval Linear momentum We consider the curvilinear motion of a particle of mass, m, under the influence of a force F. Assuming that
