- Substitution (29 Jan. 2000)

"The common element I find in most if not all of the problems
that students have that I find most baffling is some kind of
substitution... It seems like if I could understand this one
problem that it might shed light on a lot of other things.
Can anyone help?" - Shelley Walsh

The thread references an essay by Ralph Raimi, "On Solving

- DE MOIVRE'S THEOREM (2 Feb. 2000)

"Can someone provide a motivator for studying de Moivre's
theorem either (1) because the student will need it in a
future math course he/she is likely to take, or (2) because
of its application to real world problems?" - Norman Mikalac

- Indian astronomy and mathematics (14 Jan. 2000)

"Indian 'tables' of planetary parameters are lists first
appearing in treatises of the middle of the first millennium
CE. The suggested re-datings of the Vedic texts to the
fourth millennium BCE or earlier, which have been proposed
in various forms over the past couple of centuries, are
based on attributing a very high degree of precision to some
statements in them about the relation of star positions to
direction and seasons...." - Kim Plofker

mathematicians after 1000 A.D., the heliocentric model of
Aryabhata, Ptolemy and Copernicus, and more.
