**Homework Statement**

So I did an entire antiderivative, and ended with this part:

**sec(x)tan(x) + ln|sec(x) + tan(x)| + C**

I have to do this with the lower bound of -pi/3 and 0.

When I do it, I should be getting 2√3 + ln(2+√3)

But, I'm getting (0+0)-(2*-√3 + ln(2-√3))

Which would give me 2√3-ln(2-√3)

Will someone tell me where I'm going wrong?

Does it have to do with the absolute value bars?

Thanks in advance.
