National Air and Space Museum: How Things Fly. Point-Line Distance. Let a line in three dimensions be specified by two points and lying on it, so a vector along the line is given by The squared distance between a point on the line with parameter.

Weierstrass functions. Weierstrass functions are famous for being continuous everywhere, but differentiable "nowhere".

Here is an example of one: It is not hard to show that this series converges for all x. In fact, it is absolutely convergent. Professor Michael Accorsi: Parachute Simulations. What Every Computer Scientist Should Know About Floating-Point Arithmetic. This appendix is an edited reprint of the paper , by David Goldberg, published in the March, 1991 issue of Computing Surveys.

Copyright 1991, Association for Computing Machinery, Inc., reprinted by permission. Abstract Floating-point arithmetic is considered an esoteric subject by many people. This is rather surprising because floating-point is ubiquitous in computer systems. Almost every language has a floating-point datatype; computers from PCs to supercomputers have floating-point accelerators; most compilers will be called upon to compile floating-point algorithms from time to time; and virtually every operating system must respond to floating-point exceptions such as overflow.
