In 7:20 why DAC=-CBD how you determine the - minus how to determine the clock or anticlockwise

As someone in the American education system, I can confirm this was not part of our 12th grade math textbooks.

Answer is -69

You still have to show that there are a,b,c‘s to attain the 81. You can use that equality in the Cauchy Schwarz inequality holds if the vectors are linear depending and for example a=1, b=3, c=5 should work.

Can you please make a video on power of point?

Thanks a lot!! Your video made me understand my first IMO problem’s solution.

My ass did u= e^x+1, partial Fractions, and then evaluated ln(infinity) to get the same answer 💀💀

Erm what the Sigma

Can also multiply by e^x both numerator and denominator and then take e^x = t

12 class chindi questions

Easiest question fr

Easy 😂

i don’t get it

ok but how do you make sure that this is the only solution and there are no other?

Elegant solution 🎉

Ahh yes our textbook question for 12th grade.

The fact that you did the integration of lnx wrong

Shouldn't it be 1/12 instead of 1/6 🧐 ?

Nice

Cant we solve it using XBCY trapeze ?

How is xdx=ydy

We did it in 12th ! One of the easiest questions 😂😂

I guess I just found the most underrated math channel ever.

I think it’s 1/12 not 1/6 square root 2

LoL, the title😂

✅个哦哦的个✅

I just added e^x - e^x in the numerator and split it up

How tf does that prove anything

I went from x ➡ -x world Same tho

This is 12th board level question.

We literally have it in our book

Nice problem

Solved it a bit different by use of sine and cosine. Got the same thing tho. Nice problem 😊

We can also prove this by the formula of sum of 'n' numbers given by Carl Friedrich Gauss when he was just 10 years old. Let the Arithmetic progression be 1, 2, 3, 4, 5, 6, 7 ,8,...n Here, the first term=1=a Common difference=1=d Number of terms= n =n Using Gauss's formula for calculating sum of terms in an arithmetic progression, Sum of n terms= n/2[2a+(n-1)d] Substituting values we get, Sum of n terms=n/2[2(1)+(n-1)(1)] Sum of n terms=n/2(2+n-1) Sum of n terms =n/2(n+1) Sum of n terms =[n(n+1)]/2

this is literally just the dirichlet eta function evaluated at one

We do this in 12th grade.

Is it bigger than 10 {100} 10?

Cauchy schwarz inequality : (Ai^2)(Bi^2)>= (AiBi)^2

I thought of the second way but for some reason I thought u to negative u doesn't cancel out...

ye to hamare yaha boards mein aata hai😂

How do we know left side is even?

whatttt this is a qualifier question ? Bro it is just Basic question for IIT JEE student

Glad to see you back 😊

Outcome: xe^(x^3) + C

i want more question videos

Thanks for video. For MIT integration bee recently it was published a book with solutions to problems of Qualifying Tests from 2010 to 2023

Bro where is Minus sign

Bro it's too easy I guess 👍

wow

ln(2) ( i think 😅)
