a ferris wheel 24 m in diameter and boardered from a platform that is 1m above ground.
\n" ); document.write( "people enter the loading platform which is at 1m. the wheel completes 1 revolution in 10mins.
\n" ); document.write( "Use h(t) as height and t as time.
\n" ); document.write( "(A) Find the amplitude, median, and period.
\n" ); document.write( "(B) Make a cosine equation using h(t) to represent the situation.
\n" ); document.write( "(C) For how long during one cycle (period) was the height above 20m.
