This Demonstration shows a surface and intersecting vertical planes through the and axes. For the curve defined by each intersection, tangent lines at a selected point are drawn. The slopes of the tangents at that point are equal to the partial derivatives and . Cross-sections are also displayed in a two-dimensional plot.
