thank you , this integral very nice

Why is the 8 missing

The answer is correct but the method is wrong! Many youtubers also make the same mistake. You will realize your mistake when applying your method to the problem x^u - y^t = 17. You will never find the following solution of the problem 5^2-2^3=17. You also cannot find the a simple solution of the above equation is 18^1-1^18=17.The correct way to do it is as follows: We realize that x and y cannot both be even numbers or odd numbers. - If x is even number and y is odd number, we find the a simple solution of the above equation is 18^1-1^18=17 with x=18, y=1; In case x,y >= 2 => x^y≡0 (mod 4) and y^x≡17≡1 (mod 4) => y^x+17≡2(mod 4)=>x^y - y^x ≠ 17. - So the following case remains, x is odd number and y is even number => we can easily find the fist solution x=3, y=4. We will prove this is the only solution. * First, we will prove that x must be smaller than y. By examining the function f(t)=ln(t)/t, we see that this function is inverse when t>=3 => If x^y = y^x+17 > y^x then x<y. * Then, we will prove that 3^4 - 4^3 = 17 < x^y -y^x for all numbers x, y such that y>x>3 => x= 3+a and y = 4+b with b >= a >= 1 => P = x^y - y^x = (3+a)^(4+b) - (4+b)^(3+a) = (3+a).(3+a)^(3+b) - [1+(3+b)]^(3+a). Because 3+a =< 3+b => (3+a)^(3+b) >= (3+b)^(3+a) => P >= (3+a)(3+b)^(3+a) - [1+(3+b)]^(3+a) = [(3+b)^(3+a)].{(3+a) - [(1+3+b)/(3+b)]^(3+a)} = [(3+b)^(3+a)].{(3+a) - [(1+1/(3+b)]^(3+a)}. And because 3+a<=3+b and [1+ 1/(3+b)] > 1 => [(1+ 1/(3+b)]^(3+a) < [(1+ 1/(3+b)]^(3+b) < e (e=2,71828….). => P > [(3+b)^(3+a)].{(3+a) - e}. And (3+b)^(3+a) >= 4^4 = 256 => P > 256.(4-e) > 17. Q.E.D

Sir start me he Cosx ka half angle formula Tan ke terms me rakh dijiye.....fir Tanx/2 ko t let krke kr daaliye

Let,a=-129.25 d=-3/4 if we want the 20th term from the end of progression so,we can put the formula a-(n-1)d to get the answer

Literaly, Answer ko rat liya ha aapne Matlab int(1/1-V^2) likh kar tan inverse x kaise likh liya janab 😂😂[ik wo int (1/1+v^2) but fir bhi esa kuch bhi likh diya] Matlab kuch bhi bana rahe ho

You have made mistakes as AD is a angel bisector so D will bisect BC in the ratio of AB : AC. That means 1:4 But you have taken 1:2 that's wrong....... The procedure is correct 💯

Thank you sir ❤

Muzse se to bina pen paper se hi ho gya tha😂

Sir yeh direct bhi toh 0 kar skte hai odd function andar integration ke

Thanks sir

Great.

i like this series, tells us that many solvable questions were there

nice sir
