Lets start disscussion for assignment 01
share your idea
question # 2 k part 2 ka answer koi baatye ga ?? anybody ??
kiya answer nikal raha ha
first we see saddle point
sadle point main hum nay equation main say fx , fy,fxx ,fyy and fxy ka darivative lynna hai
then iss main say fx or fy k darivative equation main say pehky x ki value 0 put ker k y ki value lynni hai then y ki 0 put ker k x ki value lnni hai
then make points of function
Solve b kardo ap Sajida
main poora solve ker k ap ko dy doon gi
kuch ap wi ker lia kroo badashaa bndy j
mene 1st derivative yeh liya
f(x)=2x-2xy+2y^2
f(y)=x^2+4+4xy
2nd derivative
f(xx)=2-2y
f(yy)=4x
ab is se agy kiya kerna hoga sajida ap mjhe step by step btainge plz
Ifza f(y)=-x^2 ay ga doabara daikho
next f(xy) ka bhi lo
pher equation main pehly x=0 put ker k y ki value lynna then y=0 put ker k x ki value lynna
2x-2xy+2y^2
-x^2+4+4xy in 2no main hi put ker k value lo
ok mai
