I will make you solve max problems in Vectors and Coordinate in general via Geometry(as it's shorter and solutions are way more elegant) instead of just formulae etc. So it becomes even more important to atleast try!

Hint for 3 and 4, cos bnana h , where have I seen that in vectors🤔

Hint for 5, my favourite way of writing sine law is not a/sinA =.... But a=2RsinA. Why not prove in that direction? That is , finding "a"

Hint for 6, Running centroid straight lines proof parallely, here you need to find centroid, if G1,G2,G3,G4 are centroids of faces and G the main one, you need the ratio AG:GG1. But didn't we start 3D coordinate system, just bcuz we didn't wanna use geometry here ,as it's too complicated? So may be without using geometry!? May be tricky observation here?

Hint for 8, 1. Running parallely how u found Incenter Circumcenter in a triangle! 2.MKAH tetrahedrons ke baare mei abhi tak?? (Sirf 6. Aata h)

To all who are trying to catch up from backlogs , DONT Come live just by watching lecture and making notes , YOU ARE WASTING TIME if you are not doing situations, solving sheets attending discussion.

Better not complete the syllabus, better do 60% syllabus but by solving it's sheets.

And to this I have an interesting motivation, even I have cried over many questions, yes cried. Your confidence go into shatters , you start shaking , that's your comfort zone getting challenged! Let that happen. The only thing you can do is to not be an obstruction between the question and the destruction of the boundary of your comfort zone. Keep trying that tough ugly pathetic thing ,called your sheet,given by your monster , that's me.

Understand, you have your comfort zone , and u can be there for eternity. But a good sheet is that which challenges you to the core , the job of sheet is not to feed you at your zone. It's aim is to slowly slowly expand your zone. Expanding is painful! For that the wall of the old zone must be broken. You are the wall. You must be destroyed. You may shake , tremble , cry , get angry , frustrated. Whatever it is! You just gotta keep doing that same damn thing!🔥🥊 That's my fighter getting borned. That's a real human getting borned inside the dead one wich you are currently.

If you do it rightly , a tough sheet can make you alive! JUST LET IT HAPPEN TO YOU.

I was reading the comments and I realised many 2025 asps are still online! I meant they are on youtube! How?? Why are you even there on youtube? What are you waiting for?? Kyu nhi samajhte ho ki tumhe hi log market krte h! Kyun befkoof bnate rehte ho yaar. Adv ka karoge, in literally last week, kisi youtube ke session se??

Dekho jiska kuch hona h iss baar adv mein , wo iss time sirf problems kar raha hoga (infact wo bhi ho jaana chahiye tha bahut pehle hi) , wo kisi yt revision, problem solving session, falana dimkana ke intezaar mei nhi baitha h.

So please , don't fooled yourself further. Don't demand anything like that from MU.

Stop asking for ki sir har chapter ki problem solving krwa dijiye advanced se pehle. Nahi! And ye nhi ki mei nhi krwaunga tum agar kahin aur se bhi abhi kar rhe ho to mat karo time waste!!! I don't know how to say this as clearly as possible

Very important and interesting set of ideas in Vector 3D coming in Idea series next! You will love it for sure.❤️😎

Calculus will begin soon in MU 2026 Batch , to enroll: https://unacademy.openinapp.link/mulive-jee

3 phenomenal problems in Vector 3D which are a blast of ideas in itself! Will be discussing in Idea series soon😎

Problem 3: Find center of circumsphere of tetrahedron.

A brilliant video coming today at 8pm revising the entire VECTOR 3D unit , with all its problem solving ideas for JEE Advanced! on finding center of a sphere circumscribing tetrahedron. 7 ideas in just 1 video by just 1 problem!

Bahut time baad an actual youtube video , not just a recording

Definitely want everyone to watch it , as have compiled literally all of my favourite ideas in Vectors in one single video

Here you go!🔥😎
