👉 A contour in mathematics is a part of an object or function that represents its shape, including its asymptotes (lines where the curve approaches but never touches), inflection points, and other features. Contours are often used to visualize mathematical functions and their behavior at different points. For example, consider the function f(x) = x^2 - 4x + 3. The graph of this function is a contour that shows how it changes as we move along its curve. This is because
