A piston in an engine moves up and down in a cylinder. The height, h centimetres, of the piston a t seconds is given by the formula h= 120 sin Pi t+ 200.

-State amplitude & period

-State max & min. heights of piston

-How many complete cycles does the piston make in 30 min.

I have no idea where to start. Is this the same as y=a sin k(x+c)? Should I graph the equation as is and go from there?

Thanks in advance for any suggestions!
