Title  Determination of the tangents for a real plane algebraic curve  Author(s)  Guangxing Zeng  Type  Article in Journal  Abstract  The purpose of this paper is to present an algorithm for computing the tangents of a real plane algebraic curve. By this algorithm, all the slopes of the tangents to a real plane algebraic curve at a particular point may be accurately represented via polynomial real root isolation.  Keywords  Real plane algebraic curve, Tangent, Tangential ray, Slope, Signed subresultant sequence, Transfer principle  ISSN  07477171
