Abstract

The algorithm is presented for the determination of coefficients in the equation of the type IV conic section pencils when the pencil is given by three base points one of which is a double point. In order to work with the points in infinity, the homogeneous coordinates are introduced. The approach is illustrated by several examples.

Keywords
