You can infer all sorts of data from level curves, depending on your function. The spacing between level curves is a good way to estimate gradients: level curves that are close together represent areas of steeper descent/ascent.
The level curve corresponding to [latex]c=2[/latex] is described by the equation [latex]\sqrt{9-x^{2}-y^{2}}=2[/latex]. To simplify, square both sides of this equation: [latex]9-x^{2}-y^{2}=4[/latex]. Now, multiply both sides of the equation by [latex]-1[/latex] and add [latex]9[/latex] to each side: [latex]x^{2}+y^{2}=5[/latex].
Level Curves and Contour Plots. Level curves and contour plots are another way of visualizing functions of two variables. If you have seen a topographic map then you have seen a contour plot. Example: To illustrate this we first draw the graph of z = x2 + y2.
Unit #19 : Level Curves, Partial Derivatives Goals: • To learn how to use and interpret contour diagrams as a way of visualizing functions of two variables. • To study linear functions of two variables. • To introduce the partial derivative. Reading: Sections 12.3,12.4,14.1 and 14.2.
A level curve is just a 2D plot of the curve f (x, y) = k, for some constant value k. Thus by plotting a series of these we can get a 2D picture of what the three-dimensional surface looks like. In the following, we demonstrate this.
