15.5.4 The Gradient and Level Curves. Theorem 15.11 states that in any direction orthogonal to the gradient. ∇f(a,b) , the function. f. does not change at. (a,b) Recall from Section 15.1 that the curve. f(x,y)=.
A function has many level curves, as one obtains a different level curve for each value of $c$ in the range of $f(x,y)$. We can plot the level curves for a bunch of different constants $c$ together in a level curve plot, which is sometimes called a contour plot.
Nov 16, 2022 · The level curves of the function \(z = f\left( {x,y} \right)\) are two dimensional curves we get by setting \(z = k\), where \(k\) is any number. So the equations of the level curves are \(f\left( {x,y} \right) = k\).
Nov 10, 2020 · Determine the gradient vector of a given real-valued function. Explain the significance of the gradient vector with regard to direction of change along a surface. Use the gradient to find the tangent to a level curve of a given function. Calculate directional derivatives and gradients in three dimensions.

Check work. We often mark the function value on the corresponding level set. If we choose function values which have a constant difference, then level curves are close together when the function values are changing rapidly, and far apart when the function values are changing slowly.
