Sir please bring a video on solving area questions of coordinate geometry (JEE advanced) by using special cases, sir in those questions we have to calculate alot of coordintes and then the area, it takes atleast 10min even if you know all the process.
Sir isse better hoga we assume A & B to be the end points of latus rectum and C to be the origin and CD be the x-axis then I think we get it even faster sir ❤
Sir in your solution, you have taken A and B same points, then there are infinite lines passing through A(=B). Then why have you chosen a specific line(tangent) here??
@FlakernN aap isse aise socho ki a and b are two distinct points on parabola Then draw a line passing through a and b You will notice a sectant When we bring a and b closer and closer , they finally merge at a single point and the line joining a and b finally becomes a tangent,joki secant ka limiting case hai
#askCompetishun sir AB line segment C se pass hoke meet karni chahiye na Line L se accd to question pr apan ne aisa to nhi kiya Please correct if i am wrong
Sir I've done this under 30s. I assumed A,B as end points of Latusrectum and parabola (a,2a) , (a,-2a). C is the origin. Line L is X-axis itself, and the feet of perpendiculars both are focus of parabola. Thus answer is 36 for a=3/2.
Usually coordinate questions are lengthy but this was super intelligent method
Bang on
That was brilliant!!! I am not even writing JEE, but taking the same points as a special case to solve MCQs is too good!
Sir have you wrote any book for maths for jee advanced , if yes please tell the name please
@manjuralam-t4b 😂😂
Yes sir has a digital book
Digital book
This was awesome approach
Please keep posting such videos
Sure 👍
thanks i have been using such tricks but i can use it even more in mains
Tricks from where can u share

Sir, hum yahan A, B ko end of L.R. le sakte hain phir
AM = BN = 2a = 3 and
CD = a = 3/2
As point M,N and D is the one point, i.e. focus of parabola.
Nice short cut sir, but it would be a bit more shorter if A and B are taken on both ends of LR
Very informative and kool trick
Brilliant sir jii 😮
brilliant approach
you shud compile all these tricks in a book it will become sash-hit on DAY-1
Thank you sir ❤️🫶🏻
Love from Bihar ❤️
Sir agar a,b ko bhi origin lele ???
Sir, that's great
sir start uploading on youtube again plzzzzzzzzz
Sir ye uts ke test me bhi aya tha 😁
same question thaa kya?
@arslaanmania1309 yes
How to get solution for uts
amazing approach sir maine ek point ko origin pr mana aur dono ko latus rectum k end points but yours amazing upload these tricks sir very useful

Sir, can we also take any matrix In if it is satisfying the cond in qn?
Sir please🙏🙏 provide prakhar-2 (12th) full course planner

That's the trick man.. the question has not been specified and the examiner has given the freedom of any point.. so why not take the easiest ones....
😮😮 mind-blowing
Sir can we use end points of latus rectum as A and B and the vertex as C, as it satisfies all the conditions and the answer comes out to be same
Yeah I got 36 with that method, so works
#askCompetishun sir AB line segment C se pass hoke meet karni chahiye na Line L se accd to question pr apan ne aisa to nhi kiya
Please correct if i am wrong
Please reply
L C se pass kar rahi hai and x axis ke // hai
Wow😮
such tricks are very usefull in functional equations also we just need to guess the correct function satisfying the given conditions
Si hum A ko origin aur B,C ko ends of latus rectum maan sakte hain kya

😮
I also solved with same method😂😂
