Hi I have a question, why do you subtract equation 1 and 2 together apart from trying to get rid of h^2. How does it make actual conceptual sense, what is it showing exactly?
The proof presupposes Pythagoras theorem which is a special case of the law of cosines, making it somewhat a circular argument. There is a proof without using Pythagoras theorem from more basic principles of Euclidean geometry.
Thanks for sharing! I posted a short video on deriving the law of cosines, It should apply for all angles (acute, obtuse, reflex, negative). Hope to get your thoughts.
Really nice and simple, love it!🙂 Keep up the good work
Your explanation is so easy to understand. Thank you very much for the video.
This was interesting to know about. Thanks for sharing the proof with us.
The best. Thankyou!

if a = b and c = d then a - c = b - d because a and b are equal, and so are c and d
Nice proof, thank you.

this was super helpful!
Interesting mehn😮
Thank youu🌟❤️!

Thanks alot i needed this
Thanks Sir 🙌💯
Thanks for the proof... I never really found interest in the actually proof after I was thought when and where it was applied... thanks cheers mate
Thanks!
Thanks so much

Thanks You Alive My Problem
wow amazing
For the first time i see hope
Super
Why you have not put h^2=b^2--x^2 in eqn 2? This directly gives the required result which you want .make steps simple.
Bro, subtracting eq.2 from eq.1 is the same task what you are talking about...
Why it's 2ac then Change to -2ac
There was a minus sign before the brackets
رائع
It’s pronounced ach not hach
