Finding level curves

WebHow to determine the sign of second-order partial derivatives given the graph of level curves or contours. WebTo find the unit normal vector of a two-dimensional curve, take the following steps: Find the tangent vector, which requires taking the derivative of the parametric function defining the curve. Rotate that tangent vector 90^ {\circ} 90∘ , which involves swapping the coordinates and making one of them negative.

WebStep 1: Start with the graph of the function. Step 2: Slice the graph with a few evenly-spaced level planes, each of which should be parallel to the xy xy -plane. You can think of these planes as the spots where z z equals some given output, like z=2 z = 2 . Step 3: Mark the graph where the planes cut into it.
