Precize Solid Geometry (GNDU)


The entire subject matter in the book has been arranged in a systematic, graded, simple, lucid and exhaustive manner. Each chapter begins with some definitions followed by theorems with complete proofs and solved problems. A large number of notes and remarks have been added for a better understanding of the subject. Well-planned and exhaustive exercises have been given in each chapter.


Cylinder as surface generated by a line moving parallel to a fixed line and through fixed curve. Different kinds of cylinders such as right circular, elliptic, hyperbolic and parabolic in standard forms, Cone with a vertex at the origin as the graph of homogeneous equation of second degree. Cone as a surface generated by a line passing through a fixed curve and fixed point outside the plane of the curve, right circular and elliptic cones.

Equation of surface of revolution obtained by rotating the curve about the z-axis. Equation of ellipsoid, hyperboloid and paraboloid in standard forms. Surfaces represented by general equation of 2nd degree S = 0. Tangent lines, tangent planes and Normal plane.
