1. The part of the plane z= 6 3x 2ythat lies in the rst octant. 2. The part of the hyperbolic paraboloid z= y 2 x that lies between the cylinders x 2+ y = 1 and x2 + y = 4. 3. The surface de ned parametrically by r(u;v) = hu2;uv;1 2 v2iwith u2[0;1] and v2[0;2]. Evaluate the following surface integrals. Assume that any unit normal vectors have ...
(a) (12 points) Find an equation of the plane that passes through the three points P (1, (0,2, 1), md R = p (R PR 21 (l Pa (b) (5 points) Give the parametric equations of the line perpendicular to the plane from part (a) that passes through P.
The part of the surface z = 1 + 3x + 2y2 that lies above the triangle with vertices (0, 0), (0, 1), and (2, 1) 45. The part of the surface z = xy that lies within the cylinder x2 + y2 = 1 46. The part of the paraboloid x = y2 + z2 that lies inside the cylinder y2 + z2 = 9 · 47. The part of the surface y = 4x + z2 that lies between the A white lie is a part of good manners as sometimes it is rude to say exactly what you think. It is possible to distinguish a lie by facial expression, movements, tone of voice and other methods. Some people are sure that lies can be detected through both verbal and nonverbal means.
In parts (a) and (b) the graph of f is very flat and close to the xy-plane except near the origin; this is because e–x2 – y2 is very small when x or y is large. Quadric Surfaces The graph of a second-degree equation in three variables x, y, and z is called a quadric surface.
