Chapter 15, Problem 53(choose chapter or problem)
Use a computer algebra system to graph the torus
\(\mathbf{r}(u, v)=(a+b \cos v) \cos u \mathbf{i}+\)
\((a+b \cos v) \sin u \mathbf{j}+b \sin v \mathbf{k}\)
for each set of values of a and b, where \(0 \leq u \leq 2 \pi\) and \(0 \leq v \leq 2 \pi\). Use the results to describe the effects of a and b on the shape of the torus.
(a) a = 4, b = 1
(b) a = 4, b = 2
(c) a = 8, b = 1
(d) a = 8, b = 3
Text Transcription:
r(u, v) = (a + b cos v) cos ui +
(a + b cos v) sin uj + b sin vk
0 leq u leq 2 pi
0 leq v leq 2 pi
