00:02 Discussing Lagrange's Multipliers method with 2 variables and 1 equality constraint. 01:40 Solving equation subject to equality constraints in Linear Programming Problem 03:09 Understanding the concept of Lagrange's Multipliers 05:46 Using Lagrange Multipliers to find total objective function 07:13 Understanding Lagrange’s Multipliers for NLPP with 2 Variables and 1 Equality Constraint 09:11 Solving equations using Lagrange Multipliers 10:24 Finding maximum and minimum in a constrained optimization problem
For Equation like 12X1-lambda Use Equation option select 2 option 3 x and =dn then put the value carefully like x1 =12 , x2 = not given then 0 , x3 = lambda = -1 and dn=0 sme to all equation check second equation it has x2 directly no x1 so x1 is 0
So People who didn't understood the [12x1-lambda] part let me explain you. Note : I am using casio 991 calculator. Step 1 : press MODE Step 2 : press 5 (where Equation is written) Step 3 : press option no.2 (anX+bnY+cnZ=dn) Step 4 : Now add values of X1,X2,X3 (Eg. 12x1-lambda=0 will written as a:12 b:0(since x2 value is not mentioned) c: -1(lambda value) d: 0 Step 5 : Fill the value as step 4 Step 6 : after fill all row and column press enter and your answer is there.🎉🎉
You get 12x1-lamba =0 10x2-5lambda=0 And x1+5x2=7 Lambda=12x1 Lambda =2x2 So lambda=12x1=2x2 So x2=6x1 Can be written as 6x1-x2=0 Now the third equation which was there i.e x1+5x-7=0 Becomes x1+5x=7 6x1-x2=0 Solve simultaneously on calci and profit
When we form Lagrangian then in my book the author is putting plus sign in Lagrangian but here Prof. Using -lamda(g)..so basically tell me that it would create any difference or not?

Can I get clear explanation please???😢
how to do that on casio 991ex
😭😭😭😭😭 thankyou
brother thank u so so so so much😭😭😭
thank youuuu
For that values part refer khumbojkar page 9-10.
What is khumbojkar ?
Please prefer suitable book for preparation 😢
@@26himanshuthakur68
Kumbojkar is a good book
Thank you for your great lecture
Sir how you get these answer 9:37 plz reply
You get 12x1-lamba =0
10x2-5lambda=0
And x1+5x2=7
Lambda=12x1
Lambda =2x2
So lambda=12x1=2x2
So x2=6x1
Can be written as 6x1-x2=0
Now the third equation which was there i.e x1+5x-7=0
Becomes x1+5x=7
6x1-x2=0
Solve simultaneously on calci and profit
@@adityanair5527 could simplify it or just say how to do it in calci
@@Truth11173 Google it or use chatgpt and put ur calci model it will print out instructions or atleast similar enough for u to get it

Amazing lecture!!
how to solve lambda func on the casio 991EX ??
Thank you, sir
Can we solve these equations in calculator fx-991MS ?
Tomorrow is my optimization engineering exam
Sir, I didn't understand anything why we are doing this. This only looks like you mugged this problem and explained to us.
1st u will learn what is theory then come to learn problems
Thankyou so much sir
Are you sure sir isme x1 x2 and lemda k values shi aarhe h ?
Sir it is
L=f+lamda*g
Not ' - '
The equation does not depends on sign of lambda
Amazing!
How to put values in calci to get x1 x2 and lambda?
i think lambda = 12 && X1=1 and x2=6

Sir, delta is positive then minima and delta is negative then maxima.
How do you know???
sir did it right
delta is negative so z is minimum
X1, X2 and X3 kise aaya samja nhi plz kohi help kardo

Ye 991 nh h 961 hai sir ....
Nice try but don't try again 😞☠️
Bhai tuze chodke sbko acche se smja hai Ok
Sir how to solve this
Using Lagrange's multipliers, solve the following N.L.P.P.
1. Optimise z = 4x1 + 6x2-2x12-2X1X2-2x22
I understood all bcz I did try it somewhere else .... U just don't clarify well.... U need to improve
