## Homework Statement

f(x) = |sinx| and g(x)= |cosx|

I want the area of this between 0 and 2∏

## Homework Equations

## The Attempt at a Solution

So I'm just being careful. I just did the intervals and by doing g(x) - f(x) because it is the upper minus the lower. So, I got sinx + cosx between whatever interval I wanted. (∏/4), (3∏/4)...etc

But then I was like wait a minute. What is up with the abs.

So I'm just wondering about this. I feel like my integral is wrong if I don't account for it.

Thanks,

J
