If I have a cylinder with a radius r and an axis that passes through point b with the
direction of vector n, show that its equation can be written in any of the following forms:
1) |(p-b) X n| = r
2) (p - b) X n = r.e (where e s ia unit vector orthogonal to n)
3) |(p-b) - ((p-b).n).n| = r
. = dot product
X = cross product
Thanks in advance for any guide given...
