lol. surprisingly, i know how to do this using calc 3, but not really calc 1... let me think though
OpenStudy (anonymous):
haha that's okay, whatever works! thanks (:
OpenStudy (anonymous):
wait, so you can't do double integrals right?
OpenStudy (anonymous):
no :(
OpenStudy (anonymous):
dang... i dont know how to do this without double integrals :(... lol if you want the double integral way: all you do is SS y dydx with limits of y being lnx+4 and e^x and limits on x being the solutions to lnx+4-e^x=0

and times that by 360
OpenStudy (anonymous):
sorry
OpenStudy (anonymous):
