Sir mai patna me iit jee ka coaching karta lekin kabhi kabhi apne maths ke sir se formula ka derivation puchta hoon to wo mujhe satisfy nahi kar pate hai is video me jo aapne logically jo neeche wala angle A-B laya hai wahi apne teacher se poocha tha lekin sir satisfy nahi kar paye the islie maine youtube par compound formula derivation search kiya to ye aapka video aaya jise mujhe bahut help mila aur majaa aa gaya

[nahidaakter]

I've been searching for a good proof, but every video uses other compound formulas to prove another formula. Thank you so much for a simple explanation.

[allappayadwad]

Thank you sir your explaination made My mind free and i cleared My doubt thank you sir🙏🙏🙏

[exo-lsaranghaja]

I don't even speak Hindi but your video helped me so much thank you sir

Thanks and pranam sir aapne mera doubt solve kar diya

[pp-ftkb]

OMG 😱😱how could anyone teach like that wow 😲😲 sir your explanation was excellent and thanks a lot ❤❤ for that most useful video ❤💕💕💖

[studyadda]

Sir
Your proof included some concepts of future chapter you should explain those concept more efficiently and make it clear

[vickyshukla]

Why both the triangles are congruent? Please give satisfactory answer.

[vicky-eqrs]

Very well explained keep making more video sir and thankyou so much

[godisgood]

Yaar coaching m 1 lakh rupee dena pe bi itna acha koi explain nhi karta but aapne toh kamal h krdia

11th class mathematics important question solution Nice

[robinsoncrusoe]

Tell me how Coordinates of point P2. Here angle is greater than 90°.

[siddhartakumarjha]

At 6:20
Angle( B-A) aur angle (A-B) Same kaise hai

[kapilashhhhalwa]

Sir I can't understand that cos A-B properly

[richaroy]

hello sir nicely however, you could have focused more on the coz though u were explaining it nicely, the neatness overruled so i hope u will take care of it in the future
