Chapter 14.4, Problem 43E

To determine

Find the integral value of the function $f\left(x,y\right)=\frac{1}{\left(1-x^2-y^2\right)}$ over the disk $x^2+y^2\le \frac{3}{4}$.

Find whether the integral of function $f\left(x,y\right)$ is exist over the disk $x^2+y^2\le 1$ and provide reason for the result.
