The present book Coordinate Geometry of Two Dimensions aims at providing the students with a detailed study of Polar Coordinates, Polar Equations of a Straight Line and a Circle, Polar Equations of Conics, General Equation of Second Degree and System of Conics — the topics included in the UGC syllabus. Primarily meant for students of B.Sc./B.A. of several Indian Universities, the book exactly covers the prescribed syllabus. It neither includes the irrelevant nor escapes the essential topics. Its approach is explanatory, lucid and comprehensive. The analytic explanation of the subject matter is very systematic which would enable the students to assess and thereby solve the related problems easily. Sufficient number of high-graded solved examples provided in the book facilitate better understanding of the various skills necessary in solving the problems. In addition, practice exercises of multiple varieties will undoubtedly prove helpful in quick revision of the subject. The figures and also the answers provided in the book are accurate and verified thoroughly. A proper study of the book will definitely bring to students a brilliant success. Even teachers will find it useful in elucidating the subject to the students of Mathematics.
