GDB No.2
A new functionality (Preview) has been added in GDB to verify that your post is correctly displaying. So before posting your comments you should first preview the post and if the equations are correctly displaying then you can post the comment.
Remember once you post the comments on GDB then you cannot edit or repost your comment.
MOST IMPORTANT:
1) If a student posts his/her solution in MDB to show up others, he/she would be awarded ZERO marks. Your solution must be posted in GDB.
2) If your solution is not in Math Type, your marks will be deducted.
3) Use only Google Chrome.
Question:
Locate all the extrema and saddle points of
f(x,y)=3xy-x³-y³
Kindly Discuss here. Jazak Allah.

1) First u will find 1st order partial derivative.
2 )then 2nd order partial derivative.
3) Find the critical points setting 1st order partial derivative = 0
4) Then Solve the equation that u get from above step and find the coordinate points .
5) U will get 2 points . Now put these points in 2nd order partial derivative.
6) Now put these values in D (,) = ...... and check your pints for saddle and relative max or relative min .....
Simple ........
Have done and Submitted ..
File Me upload ai Kar Do!
Basically MTH301 is not mine Subject .... U should do your work yourself . Where u will stuck u can ask for help .. I will definitely help u ..
Hints ... U will get two points .. (0,0) and (1,1)
(0,0) is saddle point and (1,1) is relative maximum ...
question ye ha mere pas idhar wrong diya hua baqi sab logo k pas yehi ha kiya
f(x,y)=3xy−x^3−y^3
yup thats the solution
n D can be written as
D(x,y)=fxx . fyy - f^2 xy
if value will ve negative then its saddle point,
if positive n 2nd order derivative is negative it relative maximum
if d is positive n 2nd derivative is positive its relative minimum
Sorry for a little mistake...
The right question is:
f(x,y)=3xy−x^3−y^3
Please Discuss here about this GDB.Thanks
