Question

Find the domain of the function of f(x,y)= ln(16 - x^2 - 16y^2).

Answer 1

Just graph it nd that is precal right?

Answer 2

domain can be expressed as a relation between x and y

Answer 3

Well it's two variable so we can't graph it...and it's Calc 3

Answer 4

The homework has it where you fill the the blank for domain so that x and y are on the same side .... It looks like this:

Answer 5

16-x^2-16y^2>0, http://www.wolframalpha.com/input/?i=16-x^2-16y^2%3E0 domain is a circle

Answer 6

w8 not a circle, an ellipse

Answer 7

more precisely the inside of the ellipse

Answer 8

So in terms of x and y on the same side my answer would be:

(x^2)/16 + y^2 <1

Answer 9

yes

Answer 10

THANK YOU!!! :)
