The function [tex]v(t)=15\cos{3t}[/tex], [tex] 0 \leq t \leq 2 \pi[/tex], is the velocity in m/sec of a particle moving along the x-axis. Complete parts (a) through (c).

**a.**Graph the velocity function over the given interval. then determine when the motion is in the positive direction and when it is in the negative direction.

*(I have done this part)*

**b.**Find the displacement over the given interval.

*(I have done this part)*

**c.**Find the distance traveled over the given interval.

*(This is the part that I am fuzzy on)*

For this, does it involve previously found information? Or is it a separate set of calculations all its own?

Any help is appreciated!
