Mathematics
Coordinate geometry for JEE Main & Advanced — conics, lines, and clean algebra
How coordinate geometry carries heavy algebra on both papers, and how parametric forms reduce mess.
On JEE Main
Main tests standard results for parabola, ellipse, and hyperbola: tangent conditions, normal equations, and chord of contact. Questions usually have one clean numeric answer reachable from a single parametric identity.
On JEE Advanced
Advanced combines conic sections with each other, with circles, or with locus problems that require homogenisation. Multi-correct options often differ by a sign or a coefficient that only careful parametric algebra distinguishes. Integer-type questions on areas and distances reward drawing and estimation before computing.
