Give the domain for f(x,y) = ln(1-x^2 - y^2) How do you get this?
i think the domain is real
yeah i know the answer is -1<=x<1 and -1<=y<1 atleast i think, But I am unsure how to get to that
edit: yes thats the correct answer just checked with wolfram but still have no idea
would you say 1-x^2 - y^2 >0 then try to solve i would suppose
if you do that you in the end you got circle domain
which would be the correct domain
i think u have to convert it to e, coz e is a constanta, it's easier to prove
okay I got it, Just had to play around with the inequality and the x and y but It came out correct. Thanks for the help!
