Find the area of the region that lies inside both curves. $r=3sin(\Theta ),\quad r=3cos(\Theta )$

Note: You may need to assume the fact that $\lim _{M\rightarrow \infty }M^{n}e^{-M}=0$ for all n. Decide whether or not the given integral converges. $\int _{0}^{\infty }e^{-5x}dx$ The integral converges The integral diverges. If the integral converges compute its value. (If the integral diverges enter DNE.) $\square $
