## Need help please

A ship is docked in port and rises and falls with the waves.

The model h(t)=sin(PI/5)t describes the vertical movement of the ship, h, in metres at t seconds

What is the period of the function?

Determine all the times within the first minute that the vertical position of the ship is -0.9m to the nearest tenth of a second.

I'm not sure as to how im supposed to figure these out. Am i supposed to actually draw the graph to represent this or something?
