A piston in an engine moves up and down in a cylinder. It rotates at 1200 rpm (revolutions per minute).

A piston in an engine moves up and down in a cylinder. It rotates at 1200 rpm (revolutions per minute). Determine the cosine equation to model the height h centimetes of piston at time t seconds if it alternates between 0 and 60 cm in height. Assume that it starts at the axis. Include a sketch of a height vs. time graph. Show all the steps clearly to get full marks. [5 marks]
