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.🎉🎉

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

For that values part refer khumbojkar page 9-10.

[harshitmhatre]

Can we solve these equations in calculator fx-991MS ?

[hazimalkhatib]

how to solve lambda func on the casio 991EX ??

[apnosesapnotk]

Are you sure sir isme x1 x2 and lemda k values shi aarhe h ?

[MrSubodhdaronde]

Sir, I didn't understand anything why we are doing this. This only looks like you mugged this problem and explained to us.

[prasantasabar]

Tomorrow is my optimization engineering exam

[oshot]

Sir how you get these answer 9:37 plz reply

[raghavenderreddy]

Sir it is
L=f+lamda*g
Not ' - '

[cseshubhamsalunke]

Sir I solve equations through calculator but I got different values

[MayurRanshinge-em]

X1, X2 and X3 kise aaya samja nhi plz kohi help kardo

[ALKAIFANSARI-zbcs]

i think lambda = 12 && X1=1 and x2=6

[bidhichandgupta]

Sir, delta is positive then minima and delta is negative then maxima.

[vinayakbhatt]

Sir how to solve this
Using Lagrange's multipliers, solve the following N.L.P.P.

1. Optimise z = 4x1 + 6x2-2x12-2X1X2-2x22

[malikshahmahimi]

Sir ek din ke liye tumhara dimag dedona bohot zarurat hai 😂

[apnosesapnotk]

I understood all bcz I did try it somewhere else .... U just don't clarify well.... U need to improve
