Given true real numbers a & b we can calculate the distance between them using absolute value la - bl or lb - at where. 3 - c - 2 ) or numbers x eta that are a distance less than d. 2,8 or more generally strict the we change. X e ca - d , at d) inequality to heated , points xc - A very absolute common tool that is used. For any hmm a. la - c a b a c b a b c: c. 1lb - cl la - cl la . bit lb - cl la - clc la - bi adding some positive a la - bi ti. Cl amount only keeps la - cl. I t la - bl it worse he. A more useful lxtyl which you version is given by tim c triangle. E txt t ly i can get by substituting a -
