So, I don't concentrate on the class because even if I try to understand what is teaching, the teacher is so fast , bad and skipping important parts that I don't get anything. Hence, I stay chill in the class and learn all the concepts from Alakh Sir. He is true gem
Alakh sir toh acha padha hi rahe hain and that's great, but the comment section is fabulous too because you people solve each other's queries! I'm so glad, an applause for yourselves please👏👏

@@smoked8471 Cause he used i,j,k form to find dot products of vector. There are 3 forms of vector for example 3i+2j+5k (unit vector form, idk what's the exact name but i am calling this unit vector form) (3,2,5) ( coordinate form) (38^1/2) at any angle. (magnitude and angle form) We use angle in the last case. Sir use the first case to represent vector therefore normal multiplication worked. In coordinate form we use matrix multiplication. This might be not totally accurate but it should give a rough idea.

And also U are imparting education free of cost on such a huge platform without any greed. No words! Man with a big heart.
Yahan pe theta ki value nikalna possible nhi he,calculator se krne pe math error aay ga Is ka reason ye he K cos theta ki maximum value 1 he or is case me value greater than 1 aa rhi he(3÷2√2=1.06) to is ka mtlb hm ye assum kr lein ge k koi aesa angle he jis pe cos function apply ho k ye value deta hoga but in actual practice this is an error or kun k calculation k base pe ye ans aaya he lehaza hm ise wrong bh nhi kehte or ye yahein tk solve hota is k age koi step nhi lete..
u are awesome physics teacher ever seen in my life.. lots of love from America....love uhhh sir. No one here can explain as better as u.. r u bestest.!
Allakh sir is the greatest teacher of India.and we should also support him by donating some money in his account.because we give money to all the other cruption teachers also.Sir also needs support and we should provide it if we can.
He is literally legend, this year I really didn't study and my half-yearly's are just after 2 days .....after seeing his video's of chemistry and physics, I'm so confident that I'll easily score 90+. Can't thank him enough. 💖💖

27:35 answer is angle 90 degrees as Cos 90 is 0 and Dot product of the two vectors is 0, so zero divided by any number will be zero. If right then please like it
@@priyankamote5883 cos90*root 77*alpha=8alpha-4 Since,root 77×alpha×cos 90=0 Therefore,8alpha-4=0 Alpha=4/8=1/2.. |A|=root2^2+3^3+8^8=root77 |B|=root4*4-4*4+alpha^2=alpha |A|.|B|=root77×alpha Now put every thing in formula A.B=|A|.|B|cos90 And A.B=8alpha-4.

Sir thankyou so much I was not able to understand this topic but after viewing ur lecture now I am very clear
Such a nice teacher!! This was the First time i watched ur video and woww!! And also U are imparting education free of cost on such a huge platform without any greed. No words! Man with a big heart.
Yaa
24:10 answer should be cos theta=√3/2 that is equal to 30°
No..it will come 3/2 root 3
Yahan pe theta ki value nikalna possible nhi he,calculator se krne pe math error aay ga
Is ka reason ye he K cos theta ki maximum value 1 he or is case me value greater than 1 aa rhi he(3÷2√2=1.06) to is ka mtlb hm ye assum kr lein ge k koi aesa angle he jis pe cos function apply ho k ye value deta hoga but in actual practice this is an error or kun k calculation k base pe ye ans aaya he lehaza hm ise wrong bh nhi kehte or ye yahein tk solve hota is k age koi step nhi lete..
How 24:27 mod of A is calculated
@@nimraazhar6720Sahi se calculate Karo ....and 30° hi ayega.....sir se calculation me galti ho gay he...sir ne 2² + 1 + 1 ko galti se 4 likh diya he
@@nimraazhar6720 its coming 29.45 degrees... just do cos inverse 3/root12
He knows his students really well. When he told feel lelo i literally went into some another zone😂
No words for his teaching.... Thanks for clearing all the doubts😌

I can say proudly that I am completely satisfied with this video. Thanks a lot sir, for helping us in our requirement.
At 27 : 40 ans is theta = 90° ie, both vectors are perpendicular to each other ☺️
Thank you so much sir 🤩🤩🥰🥰🥰🥰😍🤗🤗🤗🤗🤗🤗🤗🤗🙂🙂🙂🙂🙂🙂🙂

Sir you are the best teacher in the pw
27:28 The answer is 90 degree
Cos 90 ka maan 0 hota hai
Allakh sir is the greatest teacher of India.and we should also support him by donating some money in his account.because we give money to all the other cruption teachers also.Sir also needs support and we should provide it if we can.
Or we can watch the ads on his video

Sir you teaching skils are amazing
You are the best teacher
It means theta is 90

He is literally legend, this year I really didn't study and my half-yearly's are just after 2 days .....after seeing his video's of chemistry and physics, I'm so confident that I'll easily score 90+. Can't thank him enough. 💖💖

What r u doing saumya now?
Did u clear jee?
27:35 answer is angle 90 degrees as Cos 90 is 0 and Dot product of the two vectors is 0, so zero divided by any number will be zero. If right then please like it
27:35 ans 90
No 0
@@sanjeevnaidu84 cos 0 =90
Now dot product concept totally clear and doubt less . thank you so much sir 🙏😊

@@priyankamote5883 hint was given in the below of questions. A.B=0
@@priyankamote5883 cos90*root 77*alpha=8alpha-4
Since,root 77×alpha×cos 90=0
Therefore,8alpha-4=0
Alpha=4/8=1/2..
|A|=root2^2+3^3+8^8=root77
|B|=root4*4-4*4+alpha^2=alpha
|A|.|B|=root77×alpha
