f(x,y)=ln(1-x^2-y^2)-x-y
a) What is the functions def.amount meaning what allowed x-values are there?
b) Find the functions stationary dots (meaning highest, lowest) and classify them.
I have tried following the examples in the book but no advance since maths really isn't my strongest side. Since I´m in university I have noone to turn to atm and this assignment is due to get handed in tomorrow. I have tried all weekend without succes, any help or pointers would be appreciated. Thanks in advance /Brian
