Sir in 2:39:40 question we can also assume both B1 and B2 vectors and individually apply the given conditions on them. Then we will get the relations between the variables and then we can easily calculate their respective values. Time taking process but still easier to think about.

can someone help me with expression? 4:49:44 Here shouldn't it be methamatically zero? because (a.b).a can also be written as mod of a square dot b? and then both expression will be same and be zero. Or am I missing something?
Here a.b is expressed as a magnitude as dot product is always a scalar quantity for example lets say a.b=5 here it says 5 multiplied by vector(a) basically directly bina dot kre u cant multiply a inside
Sir, I hope you find this comment. Sir, Mai 2025 regular school going aspirant hu. Mera syllabus almost complete hai par mere weak concepts hai aur bahut kam practice hai. School ki wajah se self study aur problem solving ka time nahi milta, saare lectures Mai beet jata hai. Jab bhi holidays hoti hai tab questions thode ho paate kyuki mera confidence gir jaata hai. Maine socha tha ki kam time ki wajah se mai crash course nhi kar paunga toh mai sirf self study kar raha hu. Kuch chapters ache jaare hai, kuch nahi aur mai bahut inconsistent hora hu. Toh mai sochra hu ki aapka nexus course join karlu since I already have plus. Par school ki wajah se mere ko darr hai ki mere ko self study ka time nahi milega but mai unguided nahi rehna chahta. Sir, aap bataye, as a regular school going student, mujhe crash course ko kaise efficiently use karu taaki mai problem solving bhi ache se kar pau aur dummy school waale baccho ke barabar aa pau.
I'm new to Sir's classes so one of the first times I heard him say 'Shera' I thought he said 'Shreya' and tab se mein bohot khush hui. Ab uska explanation mil gaya, phir bhi mein toh sochne waali hooon ki sir mujhse baat kar rahe hai, acha lagtha hai ❤
