Yet another integration question.
Hi guys, yes it's me again.

Ok I can't quite get to the answer of this question despite it being similar to the last one I sought help for, anyway here's the question:

Find (integrate; upper limit 3, lower limit -4) absolute (e^x - e^-x) dx, giving your answer to 3 significant figures.

Thanks if you could help! :)

$\int_{-4}^3 |e^x-e^{-x}|dx$
$-\int_{-3}^0 e^x-e^{-x}dx+\int_0^4 e^x-e^{-x}dx$
