TīmeklisExample 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 you ...
