Preface Proper

This discovery/invention integrates mathematical functions from first principles. It simplifies integration. Functions which can be integrated, but whose integrals are not known, can now be integrated. In the course of integration from first principles, you can develop/invent your own series, as I have developed/invented.

Anybody who has studied integration can understand this paper.

How, I discovered it: As a teacher, I was looking for the best way to teach one of my daughters, integration. Beginning with the definition of integration, which is:

a b f ( x ) d x = lim δ x 0 x = a x = b y δ x

I started by realizing that this statement is not perfect. It should actually be:

a b f ( x ) d x = lim δ x 0 x = a x = b f ( x n ) δ x

where f(xn) is a particular height from the curve to the x-axis.

I carried on working along side my other duties, and within two months, I produced different function types, taught in the high school.
