CPM Homework Help : CALC Problem 6-116

Find the area between the curves $y =\operatorname{sin} x$ and $y =\operatorname{cos} x$ on the interval $[ \frac { \pi } { 4 } , \frac { 3 \pi } { 4 } ]$ .

Hint:

You know the bounds. But do you know what happens between the bounds? Which function is on top and which is on the bottom?

More Help:

Area between curves $=\int_{A}^{B}((\text{top function})-(\text{bottom function}))dx$
A $=$ left-most bound
B $=$ right-most bound
