Better prestige, larger customer current capacity and more benefits can be obtained with the operation of point integral management in the department store.
百货店通过点积分的管理获得客户更好的信誉,增加客户流量,获得更多的利益。
P1 If we have a curve c, from a point p0 to a point p1 then the line integral for work depends only on the end points and not on the actual path we chose.
如果曲线c,起点为P0,终点为1,那么计算所做功的线积分,只与端点位置有关,而与我们选择的路径无关。
OK, so the claim is if I have a line integral to compute, that it doesn't matter which path I take b as long as it goes from point a to point b.
也就是,如果我需要计算一个线积分,无论我取怎样的路径,只要路径是从点a到点。
We want to integrate. So let's take the integral of both sides, going from the initial point to the final point.
分别从初态,到末态做积分,消去微分。
