Maths is really not about just memorizing concepts , like in Class IX , there is no derivation for the Heron’s formula in the syllabus but just verification with the contemporary formula . Thank you so much sir for bringing out the concept of mathematics into proof and deriviation , because Maths always starts with a question , and ends with a reason

Here's another method from the derivation for the area of triangle As we got x=(a^2-b^2+c^2)/2b. Substitute the value in h^2=a^2-x^2 =h^2=a^2-{(a^2-b^2+c^2)/2b}^2 =h^2=a^2-(a^2-b^2+c^2)^2/4b^2 Take the lcm =h^2={4a^2b^2-(a^2-b^2+c^2)^2}\4b^2 So h=√{4a^2b^2-(a^2-b^2+c^2)^2}\4b^2 h=√{4a^2c^2-(a^2-b^2+c^2)^2}\2b Substitute h in 1/2×b×h where base=c =1/2×c×√{4a^2b^2-(a^2-b^2+c^2)^2}\2b =c×√{4a^2b^2-(a^2-b^2+c^2)^2}\4b (for the triangle a∆b base-c)
No you are the one who doing it wrong. If A² = x²+h² then h² should be a²-x² because after transferring of x² in LHS, it's sign changes into -x² So it will ve -x²+a², can also be written as a²-x²
Wow sir beautiful explaination. First time then second time I can't understand. But when I paused the video and thought for a while I understood each and everything. Thanks sir

I don't like you sir
Sir godly explanation❤❤❤
Thank you so much
Here's another method from the derivation for the area of triangle
As we got x=(a^2-b^2+c^2)/2b. Substitute the value in h^2=a^2-x^2
=h^2=a^2-{(a^2-b^2+c^2)/2b}^2
=h^2=a^2-(a^2-b^2+c^2)^2/4b^2
Take the lcm
=h^2={4a^2b^2-(a^2-b^2+c^2)^2}\4b^2
So h=√{4a^2b^2-(a^2-b^2+c^2)^2}\4b^2
h=√{4a^2c^2-(a^2-b^2+c^2)^2}\2b
Substitute h in 1/2×b×h where base=c
=1/2×c×√{4a^2b^2-(a^2-b^2+c^2)^2}\2b
=c×√{4a^2b^2-(a^2-b^2+c^2)^2}\4b (for the triangle a∆b base-c)
I think that u should make a UA-cam video on it... No one will read such long comment... Make a video. ☺☺😊😊
We will read
Bahut hi jyada Mehmet kra he bahi👍🏻👍🏻😅😅
I love your teaching ❤❤❤❤❤❤❤sir
Sir earlier we used to remember the formula but now we watch many of your videos and never forget the formula so helpful 💜
Very good and helpful video ❤❤
Very informative video sir❤❤❤😊
Wonderful derivation.. Hats off

Really helps me
Thank you sir
Glad to hear that
Maja aaya sir❤❤😊
I have a doubt sir
At 2:55s, in equation 1,
A square=X square+H square
Then,
H square=X square-A square
I think it's a mistake sir
No you are the one who doing it wrong. If A² = x²+h² then h² should be a²-x² because after transferring of x² in LHS, it's sign changes into -x² So it will ve -x²+a², can also be written as a²-x²
@@overallperfect777 TQ sir
Nice as Ever
I have a question what will be area if triangle with sides 4m , 10 m and 5m ❓
Jai Hind 🇮🇳 Jai Bharat 🇮🇳
Jai Mahakal 🔱
Not possible
Because of inequality of triangle
Not possible because two sides should add up and should be greater than then third side 4+5
Wow sir beautiful explaination. First time then second time I can't understand. But when I paused the video and thought for a while I understood each and everything. Thanks sir
