1. The problem statement, all variables and given/known data [tex]\int(2dx/(x^2+4)[/tex] from x= -[tex]\infty[/tex] to x=2 2. Relevant equations No specific ones. 3. The attempt at a solution So, from there I tried to split the integral into two, integrating between 2 and -2, and -2 and -[tex]\infty[/tex], but I got very lost trying to take the limits for these, partly because I don't know what to set as the approaching variables in each case. And integrating the function actually is another issue. Could someone take a look?
