Curve A is defined as $\ln (x^2 + 4)$ Find the region bounded by curve A, positive X axis and Y axis. My attempts, I've drawn the function, split it into two parts and found out that it's the area between curve $\ln (x2)$ , x axis and y axis. How do I integrate, using what limits? Thanks!! The answer is $4 \ln ( 2 + \surd 3)  2 \surd 3$.
