Assume Further That The Bottoms Of The Two Valleys Are At The Same Height Z K Draw Sketch The Level Curves For Z K Z 1 (110.92 KiB) Viewed 22 times

Assume further, that the bottoms of the two valleys are at the same height z=k. Draw/sketch the level curves for z=k, z=k+1, z=k+2. What is special about the level curve when z=k? On Wednesday, we will talk about this in detail. But argue why we call z=k tangent plane for each of the two bottom points'.
