Equation of a level curve
WebJan 27, 2024 · By definition, a level curve of f(x, y) is a curve whose equation is f(x, y) = C, for some constant C. It is the set of points in the xy -plane where f takes the value C. Because it is a curve in 2d, it is usually easier to sketch than the graph of f. Here are a couple of examples. Example 1.7.5. f(x, y) = x2 + 4y2 − 2x + 2 WebOct 10, 2015 · We can use the partial derivatives of f to write a linear approximation of f near some point on the level curve, ( a, b). This linear approximation would be: L ( i, s) = f ( a, b) + [ f x ( a, b)] ( i − a) + [ f y ( a, b)] ( s − b)
