A message to faculty:
|
We
present a short video which may be used in a Calculus, Analysis, or
History of Math. After first discussing the historical
development of the epsilon-delta definition, the video then briefly
takes students through the underlying visual logic.
We
wish to reassure faculty that we consider the video as only an initial
introduction to a definition of the limit. We leave it to the classroom
professor to lead students in a precise discussion of rigor in
the theory of limits.

"One magnitude is
said to be the limit
of another magnitude when the second may approach the first within any
given magnitude, however small, though the second magnitude may never
exceed the magnitude it approaches."
D'Alembert
in
his
article on the term limit in
the famous French Encyclopédie.

Errata:
- Spelling error:
"Issac Newton" should be "Isaac Newton."
- The precise quote
from Berkeley is: "And what are these Fluxions . . . may we not call
them the ghosts of departed quantities?"
- Weierstrass
(1815-1897), the "father of modern
analysis," was working in the mid to late
1800's. His "ε - δ" terminology has become standard
universal notation.
