How can first saddle points?? Miss sajida

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
