25/2/04 Example 5 The level curves of f(x,y) = x 2 y 2 are curves of the form x 2 y 2 =c for different choices of c These are circles of radius square root of c Several of them are shown below One can think of the level curve f(x,y)=c as theNeed to translate "LEVEL CURVES" from english and use correctly in a sentence?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 On this graph we draw contours, which are curves at a fixed height z = constant For example the curve at height z = 1 is the circle x2 y2 = 1
