Understanding Math Rather Than Merely Learning It

The Error Function & The Integral of e^(-x^2)

The Bell Curve:

Improper Integral vs. Infinite Series

To test if the infinite series converges,
provided the function
in the interval [2, ∞[ is:

• positive &
• decreasing function

you can convert it to
(although they converge to different values.)
