Hello
im stuck with this problem and badly need help:
$\displaystyle \int_{-3}^{3} \sqrt{3+|x|} dx$
Good morning Adam:
You can break it up into two integrals. That's mostly the best with an absolute value.
Since it's symmetrical about the y-axis:
$\displaystyle 2\int_{0}^{3}\sqrt{3+x}dx$
Or
$\displaystyle \int_{-3}^{0}\sqrt{3-x}dx+\int_{0}^{3}\sqrt{3+x}dx$
