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 WebJan 27, 2024 · 1.6: Curves and their Tangent Vectors.

WebA line has equation 4x + y + k = 0 and a curve has equation y = kx² + 3, where k is a constant. a) Find the two values of k for which the line is a tangent to the curve. b) Find the equation of the straight line joining the points on the curve for these two values of k. Weby - 8 = 12 (x - 2) since the gradient of the tangent is 12 and we know that it passes through (2, 8) so y = 12x - 16 You may also be asked to find the gradient of the normal to the curve. The normal to the curve is the line perpendicular (at right angles) to the tangent to the curve at that point.

A circle with center ( a,b) and radius r has an equation as follows: ( x - a) 2 + ( x - b) 2 = r2 If the center is the origin, the above equation is simplified to x2 + y2 = r2 The above equations are referred to as the implicit form of the circle. The parametric form of a circle is

WebWe will examine the level curves of z = f ( x, y) . Setting z = k, k ≥ 0, squaring both sides of the equation and rearranging terms, we find that the level curves of z = f ( x, y) are circles given by x 2 + y 2 = 9 – k 2 . Examination of traces with x = c or y = c shows them to be portions of circles. Thus, z = f ( x, y) is a hemisphere here.
