Hmmmm I'm not familiar with seeing absolutes in integrals either. I think this is how we would deal with it though. Think about the function \(y=x\). It's a Vshape, formed by 2 lines, \(y=x\) when \(x \lt0\) and \(y=x\) when \(x \gt0\). So I think we can replace the abs(x) with x when our integral is dealing with values of x which are less than 0. And then also replace abs(x) with +x when we're dealing with positive values of x. Let's start by splitting up the integral.\[\large \int\limits_{1}^3 \frac{x}{x}dx \qquad \rightarrow \qquad \int\limits_{1}^0 \frac{x}{x}dx+\int\limits_{0}^3 \frac{x}{x}dx\]

Notice that we're dealing with NEGATIVE x's in the boundaries of the first integral, and POSITIVE x's in the boundaries of the second. \[\large \int\limits\limits_{1}^0 \frac{x}{x}dx+\int\limits\limits_{0}^3 \frac{x}{x}dx\]

I think that's what you're suppose to do.... I'm not positive though :3
