end-point line translation 端点平移直线
two end point connecting line 两端点连线
Line End Point 线端点
Line end point prompt 拾取末尾点
Well, if I have a gradient field, then if I try to compute this line integral, I know it will be the value of the function at the end point minus the value at the starting point.
如果有一个梯度场,然后想计算线积分,我知道积分值是,起点的函数值减去终点的函数值。
Then use the lineTo API to draw a line from the start point to the end point passed in to the lineTo call.
然后使用lineTo API来从这个起始点到传递到这个lineTo调用中的端点之间绘制一条直线。
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。
