Overview — Analytical Geometry by P.N. Chatterjee (PDF)
Why it's useful: Clear worked examples, many exercise problems across difficulty levels, good for exam prep in undergraduate calculus/geometry courses and competitive exams that test coordinate-geometry skills.
Always draw a rough sketch for 2D problems (circles, lines intersecting).
For 3D, visualize the orientation. P.N. Chatterjee includes diagrams; replicate them in your notes.
