Roman sir, I wrote the plan -"devil is in the detail" I followed it initially but recidivism crept in. I found it useful. lokking forward to shred the plan after following it completelty. Also the "Not today I will do it tomorrow" positive procrastination also helped
PM Kaise nikale ho sir ?
sir Mera 11 weak hai aur abhi Maine 12bka BOARD complete kiya hai.......what should be my strategy

Focus on string areas ... If u focus on weak areas in this less time ..ur strong areas will also become weak by then
sir, in q.no. 2 if we know the coordinate of p then we can find the distance but a/c to q. we know the coordinate of S??????

  7. REVISION COURSE FOR JEE MAIN AND ADVANCED (IIT-JEE) Conic Section - Definitiorn P(h, k) A conic section or conic is the locus of a point P which moves in such a way that its distance from a fixed point S always bears a constant ratio to its distance from a fixed straight line, all being in the same plane. S( , ) SP -=constant = e (eccentricity) PM SP= e. PM e= 1 : Parabola e< 1 Ellipse e>1: Hyperbola e -0:Circle (special case ofellipse) Z' MATHEMATICS FOR IIT-JEE ER. VINEET LOOMBA (IIT RooRKEE)

  11. REVISION COURSE FOR JEE MAIN AND ADVANCED (IIT-JEE) Solved Example The equation of the conic with focus at (1, -1), directrix along x-y+1-0 and with eccentricity 2 is (a) x2-y2=1 (c) 2xy 4x +4y +1-0 (d 2xy +4x -4y -1 0 (b) xy=1 (c) Let P (x, y) be any point on the conic. Then (x-1), (v +1)2 = J2| x-y +1). [Using SP = e.PM] V2 2xy-4x+4y + 1 = 0. MATHEMATICS FOR IIT-JEE ER. VINEET LOOMBA (IIT RooRKEE)
