This week’s math fact of the week is an interesting trigonometric identity involving the tangent function that I happened across the other day while reading the Polymathematics archives. Given a triangle with angles A, B, and C:

That’s a pretty neat identity! But how can we show it to be true? You can read a simple [...]

Hello again, fellow math fans! Welcome again to another installment of math fact of the week. This week, we have our very first math joke of the week (I love a good math joke). I found this particular math joke while browsing the excellent MathWorld, a fantastic mathematics encyclopedia edited by Eric W. Weisstein. MathWorld [...]

There is no smallest real number greater than zero.
