Original question Find an equation of the level curve of f(x,y) = yx^2 – y^2 through the point (2,1) and find an equation of the tangent line to the level curve at this point I think I have found the equation of the tangent line to the level curve 10 = 4x 2y (is this correct??), but I have no idea how to find the equation of the level curveGradient is perpendicular to the level curves) Note, this problem is strictly about 2D functions w = f(x, y) and their gradients and level curves Also note, for Answer Suppose w = f(x, y) and we have a level curve f(x, y) = c Implicitly this gives a29 Exact Equations and Level Curves 151 29 Exact Equations and Level Curves A level curve or a conservation law is an equation of the form U(x;y) = c Hikers like to think of Uas the altitude at position (x;y) on the map and U(x;y) = cas the curve which represents the easiest walking path, that is, altitude does not change along that route
Level Curves Author Kristen Beck Topic Functions This worksheet illustrates the level curves of a function of two variables You may enter any function which is a polynomial in both andIf you're working with some other 3D graph then, you'll want to check to find which values of x and y together produce z The easiest way to do this is to set a fixed value for one variable and then solve for the other So, if you have a function F (x,y) = 2x 3y, and you want toSolution The level curves of are curves in the plane along which has a constant value We now sketch the resulting curves for a couple values of The curve consists of all points satisfying That is, it has points where or Similarly, the and level curves are given by and Hence our sketch of the level curves of looks like

A level curve of a function f (x,y) is a set of points (x,y) in the plane such that f (x,y)=c for a fixed value c 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 cExample 1 Let f ( x, y) = x 2 − y 2 We will study the level curves c = x 2 − y 2 First, look at the case c = 0 The level curve equation x 2 − y 2 = 0 factors to ( x − y) ( x y) = 0 This equation is satisfied if either y = x or y = − x Both these are equations for lines, so the level curve for c = 0 is two lines If youLevel Curves One of the most useful and common methods for visualizing functions (or surfaces) of two varibles is a Contour Map in which points of constant elevation are joined in a 2D plane to form level curves (or contour curves)

The level curves (or contour lines) of a surface are paths along which the values of z = f (x,y) are constant;Ie 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 surface Examine the level curves The level curves of the function z = f (x,y) z = f (x, y) are two dimensional curves we get by setting z = k z = k, where k k is any number So the equations of the level curves are f
