Level curves calc 3-So level curves, level curves for the function z equals x squared plus y squared, these are just circles in the xyplane And if we're being careful and if we take the convention that our level curves are evenly spaced in the zplane, then these are going to get closer and closer together, and we'll see in a minute where that's coming fromThe level curves (or contour lines) of a surface are paths along which the values of z = f (x,y) are constant;

The level curves f = c, 0 <U(x;y) = cas the curve which represents the easiest walking path, that is, altitude does not change along that route The altitude is conserved along the route, hence the terminology conservation law Other examples of level curves are isobars and isotherms An isobar is a planar curve where the atmospheric pressure is constant An isotherm is a planar curve along which the temperature isLevel curvesInstructor David JordanView the complete course http//ocwmitedu/1802SCF10License Creative Commons BYNCSAMore information at http//ocwm

Level curves Level Curves For a general function z = f ( x, y), slicing horizontally is a particularly important idea Level curves for a function z = f ( x, y) D ⊆ R 2 → R the level curve of value c is the curve C in D ⊆ R 2 on which f C = cThat is, x 2 y 2 = c Because x 2, y 2 ≥ 0, the above equation has a solution when c ≥ 0 When c ≥ 0, the above equation is the equation of a circle of radius c centered at ( 0, 0)This problem has been solved!

Level Curves
Level curves are points (x,y) that give f (x,y) a constant value That is the same as 2xy= c (x 2 y 2 or x 2 (2/c)xy y 2 = 0 Obvious point if c= 1 that is x 2 2xy y 2 = (x y) 2 = 0 which is the single straight line y= x It should be easy to show that for other values of c, it can still be factored and the graph will be twoIe the level curves of a function are simply the traces of that function in various planes z = a, projected onto the xy plane The example shown below is the surfaceIe tex 1 = \\frac{9}{1 c^2} x^2 \\frac{4}{1 c^2}y^2/itex for V(x, y) = c = constant I feel so
