Question: Is it possible to calculate the Pythagorean Formula without the use of a square root function? source

In order to support Geokit in sqlite3, I need a way to calculate distances that does not require cosine or square root. In my problem space, the points are relatively close to each other.

C1=A+B

The error was very similar to the size of the lowest number. So subtracted a fraction of the lowest number.

C2=A+B-min(A,B)*0.6

Restated the formula with min and max, and tweaked the ratios.

C3=max(A,B)*0.945 + min(A,B)*0.415
