I need a good book for studying analytical geometry which involves 2d geometry , conic sections, 3d geometry, quadroids, conicoids, locus etc at UG level and helpful for GMAT prep also.
There is no one such book but I will suggest you few books that will help you to learn and will help for GMAT.
1) Analytical Geometry: With the Properties of Conic Sections, and an Appendix, Constituting a Tract On Descriptive Geometry by John Narrien (2010 – Nabu Press)
2) Calculus with Analytical Geometry for the Technologies (Prentice Hall Series in Technical Mathematics) by Lawrence M. Clar and James A. Hart (1980 – Prentice Hall)
3) Analytical Geometry: Two and Three Dimensions by D. Chatterjee (2009 – Alpha Science International Limited)
