Another way of solving this que is by considering odd and even terms seperately. Then by S(1-1/x²) we simply get two gp from which we directly get (x-1)²x²⁰²⁰ -2/x²+2/x By this min value can be easily calculated by dy/dx
After summing up all the terms of f(x) , we get a closed form as f(x)=(x^2024+2024x+2023)/(x+1)² Clearly x=1 and x=-2024/2022 are the only critical points,(from the general expression of f(x) we see that f(x)>2023 for all x
I belive that f(1) will be the only minima because: 1)Negative numbers are eliminated 2)for numbers ranging from x=[0,1) f(x)~2022 [f(0)=2022] because for 0
If you estimate f' from [0,1] then it will bear a negative value means f is decreasing function in [0,1] similarly, f is increasing in (1, 2] , f' will bear +ve value Hence we can say that 1 is global minima of the above function
Brother agp method se we can directly deduce 1 as global minima…just x^n -1 ki identity use hori hai last me…2-3 lines of differentiation and the job is done👍🏻
( 7 minutes ) Approach 1 : Modular congruence, factor theorem, elementary group theory .. Let there be a group of all such polynomials .. Let Fi(x) be a polynomial belonging to the group. You notice : F0=1x^0 F2 = (x-1)^2+2 F4=(x-1)^2*q(x)+3 F2i gives remainder i+1 when divided by (x-1)^2.. Putting i = 1011 ,u get the mentioned polynomial and remainder is 1012 which obviously is the minimum value when x=1.
Bhaiya jo aapko email me 15-20 question aaye vo hamare saath bhi share kardo 🥺 I am also passionate about maths and wanna try to solve those questions ❤️
There is some analysis to be done by checking what happens when numbers before and after 1 are put into the expression. If we first simplify the expression to x^2021(x-2) + x^2019(3x-4)+....x(2021x-2022) + 2023. When we put 1, we get 1012 as you have stated. Trying something less than 1 say 0.99 will essentially reduce the higher powers of x to near zero as such all the stuff that was going to be subtracted from 2023 will be reduced which will result in value higher than 1012 and if we were to put something greater say 1.01, then the lower powers will be reduced like (2021 -2022) which would be -1 will now be now around 19 as such this will also affect our answer. I know this is not a rigorous proof but i feel its a decent enough reason to assume that 1 will be the answer.

I was so immersed into the story that I almost forgot to pause 😂 Anyways heres my solution development: if we take x²⁰²²common we have (1- 2/x + 3/x² - 4/x³...2023/x²⁰²²) , In general do you know the formula for 1-2x+3x²...(-1)ⁿnxⁿ-¹?

I got {2023+2024x+x²⁰²³){1/(x+1)²} as f(x) , I took the derivative and tried putting x=1 in the solution which turned out to be 0 , now clearly for any number greater than 1 this would shoot up to a very big number because I had the remaining polynomial part of f’x as 2021x²⁰²³+2023x²⁰²²-2022x-2022 , these powers become useless between (0,1) but if you put something greater like x=2 the powers would be tremendously huge and hence f'(x) will continue to stay positive and also x cant be negative because for any -ve number its +ve counterpart is guaranteed to yield a lesser value , Therefore x=1 yileds the global minimum value being 1012 Edit: Your solution was so ingenious lol much better, in your solution in the form you wrote as f(x) putting x≥2 would give a +ve answer for all the individual brackets and + 2023 so they cant be minimum

We can just write the derivative in the form of sigma (2023-r)(r)(x^(r-1)-1)= sigma(2023-r)(r)(x-1)(1+x+x^2+x^3+.....+x^(r-1)) and so the only values of x for which derivative is 0 are -1 and 1 but as we identified that it is between 0 and 2 so the answer is therefore 1.
Putting 1.1 in f'x will give us a positive number i.e slope positive however putting 0.9 will give us a negative number hence negative slope we can infer that x=1 is global minima 🙃
So as we know that it will ocuur in the interval [0,2] and 1 is the critical point. So, f(0)=2023 f(2)= greater than 2023 f(1)=1012 And hence we can say that at x=1 global minima is present.
Observing the question we find that this eqation never be negative and sum of last rth term and first rth tearm s sahgunak is 2024 and sign become opposite when we move to center then we put 1 the we get 0 which is least value of function .. we easely solve by obsevation

To find the minimum value of the function \( F(x) = x^{2022} - 2x^{2021} + 3x^{2020} + \ldots + 2023 \), we need to find the critical points by taking the derivative of the function with respect to \( x \) and then setting it equal to zero. First, let's find the derivative of the function: \[ F'(x) = 2022x^{2021} - 2 \cdot 2021x^{2020} + 3 \cdot 2020x^{2019} + \ldots + 0 \] \[ F'(x) = 2022x^{2021} - 2 \cdot 2021x^{2020} + 3 \cdot 2020x^{2019} + \ldots \] Now, to find the critical points, we set \( F'(x) \) equal to zero: \[ 2022x^{2021} - 2 \cdot 2021x^{2020} + 3 \cdot 2020x^{2019} + \ldots = 0 \] Factoring out the common term \( x^{2019} \): \[ x^{2019}(2022x^2 - 2 \cdot 2021x + 3 \cdot 2020) = 0 \] \[ x^{2019}(4044x^2 - 4042x + 6060) = 0 \] Now, to find the critical points, we need to solve the quadratic equation \( 4044x^2 - 4042x + 6060 = 0 \). After finding the roots, we need to check which one minimizes the function. However, due to the very high degree of the polynomial and the specific values involved, it might not be practical to solve it algebraically. Instead, considering the leading term \( x^{2022} \), which has a positive coefficient, we can infer that as \( x \) approaches positive or negative infinity, \( F(x) \) also approaches positive infinity. Hence, there is no minimum value for this function. . Let's continue with a different approach to find the minimum value of the function. Given the function: \[ F(x) = x^{2022} - 2x^{2021} + 3x^{2020} + \ldots + 2023 \] Notice that each term has a decreasing exponent but an increasing coefficient. To find the minimum value of the function, we can consider the term with the lowest exponent, which is the constant term, \( 2023 \). Since all other terms involve \( x \) raised to a higher power, they will dominate the function as \( x \) approaches positive or negative infinity. Therefore, we can conclude that the minimum value of the function occurs when \( x = 0 \). Substituting \( x = 0 \) into the function, we get: \[ F(0) = 2023 \] So, the minimum value of the function \( F(x) \) is \( 2023 \).
x=1 is the global min because for x2 f(x ) is greater than 2023 and therefore if we consider points around x= 1 we get that the min value of fxn will be at x=1 , i.e it is the global minima ... Awesome qn btw

Kaha Mila tha bhai tumko yeh sawaal
After summing up all the terms of f(x) , we get a closed form as
f(x)=(x^2024+2024x+2023)/(x+1)²
Clearly x=1 and x=-2024/2022 are the only critical points,(from the general expression of f(x) we see that f(x)>2023 for all x
In the denominator of f(x) it should be (x-1)² and not (x+1)²
I belive that f(1) will be the only minima because:
1)Negative numbers are eliminated
2)for numbers ranging from x=[0,1) f(x)~2022 [f(0)=2022] because for 0
ig because the function is increasing in lhs and rhs of 1 so it will be global minima

Bahut achha sawaal tha ye
1 is only solution as f'(x) is zero only at x=1 in [0,2]
( mujhe solve karna nhi aya per desmos par check karke pata chala 😢)
Respect the honesty bro
Isko binomial se bhi kar sakte the btw.. zyada asan parta
7:03 bhaiya yaha pe app kaise dekthe hi bataya ki vo even no.of terms hai
Orginal series ko dekhe to power 2022 se start Hui thi aur end hui power 0 ( constant term par ) mtlb 2023 terms in total sab dy/dx or differentiation kiya constant term ka differentiation 0 hogya aur no of terms 1decrease Hui toh total no of terms then 2022 hogayi so we can no of terms are even after dy/dx
Or simply you can think har term cancel hogi 1st and last jaise toh no of terms even honi padegi tabhi isa possible ha
U should take help of sandal bhaiya
Abeyyyy ye tohh mere coaching ke mock test ka question h😂
Bhaiya bg music low rakho

Very simple question

To find the minimum value of the function \( F(x) = x^{2022} - 2x^{2021} + 3x^{2020} + \ldots + 2023 \), we need to find the critical points by taking the derivative of the function with respect to \( x \) and then setting it equal to zero.
First, let's find the derivative of the function:
\[ F'(x) = 2022x^{2021} - 2 \cdot 2021x^{2020} + 3 \cdot 2020x^{2019} + \ldots + 0 \]
\[ F'(x) = 2022x^{2021} - 2 \cdot 2021x^{2020} + 3 \cdot 2020x^{2019} + \ldots \]
Now, to find the critical points, we set \( F'(x) \) equal to zero:
\[ 2022x^{2021} - 2 \cdot 2021x^{2020} + 3 \cdot 2020x^{2019} + \ldots = 0 \]
Factoring out the common term \( x^{2019} \):
\[ x^{2019}(2022x^2 - 2 \cdot 2021x + 3 \cdot 2020) = 0 \]
\[ x^{2019}(4044x^2 - 4042x + 6060) = 0 \]
Now, to find the critical points, we need to solve the quadratic equation \( 4044x^2 - 4042x + 6060 = 0 \). After finding the roots, we need to check which one minimizes the function. However, due to the very high degree of the polynomial and the specific values involved, it might not be practical to solve it algebraically.
Instead, considering the leading term \( x^{2022} \), which has a positive coefficient, we can infer that as \( x \) approaches positive or negative infinity, \( F(x) \) also approaches positive infinity. Hence, there is no minimum value for this function.
. Let's continue with a different approach to find the minimum value of the function.
Given the function:
\[ F(x) = x^{2022} - 2x^{2021} + 3x^{2020} + \ldots + 2023 \]
Notice that each term has a decreasing exponent but an increasing coefficient. To find the minimum value of the function, we can consider the term with the lowest exponent, which is the constant term, \( 2023 \). Since all other terms involve \( x \) raised to a higher power, they will dominate the function as \( x \) approaches positive or negative infinity. Therefore, we can conclude that the minimum value of the function occurs when \( x = 0 \).
Substituting \( x = 0 \) into the function, we get:
\[ F(0) = 2023 \]
So, the minimum value of the function \( F(x) \) is \( 2023 \).
x=1 is the global min because for x2 f(x ) is greater than 2023 and therefore if we consider points around x= 1 we get that the min value of fxn will be at x=1 , i.e it is the global minima ... Awesome qn btw

All people who gave reason for x=1 to be min, all are blatantly flawed.
yea, most of them 😂

this was the hardest problem ? and this youtuber, who seems to consider himself a pro problem solver did so much melodrama to solve " this " question ??!! Its pathetic.... isse acha bhai primary school ki mental maths solve karta... udhar melodrama accha bhi lagta.......
Bhai I am not a pro problem solver, auto assume karlete ho.
I just enjoy solving questions. Cuz its fun. besides, It ain’t the hardest but its fun 😍
