Set x=0x=0 to see the trace of the ellipsoid in the yzyz-plane. To see the traces in the xyxy–and xzxz-planes, set z=0z=0 and y=0y=0, respectively. Notice that, if a=ba=b, the trace in the xyxy-plane is a circle. Similarly, if a=ca=c, the trace in the xzxz-plane ...
A region in the plane representing a lamina. To find the center of mass of a lamina, we need to find the total mass of the lamina, as well as the moments of the lamina with respect to thexx– andyy-axes. Center of Mass of a Thin Plate in thexy-Plane LetRdenote a re...
如图中,点 在图中, 分别表示 与面 的交线,而 就是在点 处的对应曲线的切线, 在 上的切平面(tangent plane)可定义为 所确定的平面 假设 点处的切平面满足 令 那么 代表一条直线,那么按照定义 应该等于 类似地,令 因此: 在点 的切平面方程应满足 线性近似 利用上面的结论,在 极小的邻域内,我们可以认为...

Level curves are always graphed in the xyxy-plane, but as their name implies, vertical traces are graphed in the xzxz–or yzyz-planes.Definition Consider a function z=f(x, y)z=f(x, y) with domain D⊆R2D⊆R2. A vertical trace of the function can be either the set of points ...
