Recorded use
Wiktionary examplesThese source excerpts show how affine appears in context. They illustrate usage; the definition above remains the entry’s reference meaning.
Now, let P, Q, and R be three noncollinear points that are left fixed by an affine transformation T.
In our example of the affine cryptosystem family, deciphering is also accomplished by an affine map, namely P#92;equiva#123;-1#125;C-a#123;-1#125;b#92;bmodN, and so the deciphering transformation uses the same algorithm as the enciphering transformation, except with a different key, namely, the pair (a#123;-1#125;,-a#123;-1#125;b).
Etymology
From Latin affinis (“connected with”).
