Chapter 14: Q 5 (page 1149)

Give an intuitive explanation of why the paraboloid $z = x^{2} + y^{2}$ is smooth but the surface of the rectangular solid bounded by the coordinate planes and the planes $x = 14, y = 5, and z = 32$ is only piecewise smooth.

Step by step solution

Given Information

It is given that $z = x^{2} + y^{2}$ ,

$x = 14, y = 5, z = 32$ is piecewise smooth.

Explanation

There is always well defined choice of vector on surface of paraboloid. Hence given paraboloid is smooth.
Solid which is a rectangle is piecewise smooth, intersection of these forms corners which are sharp. Hence, these corners have not well defined normal vectors.
So, the rectangular solid that is bounded by coordinate planes and given planes $x = 14, y = 5, z = 32$ is piecewise smooth.
