Ok now this problem is
A piston in a large factory engine moves up and down in a cylinder. The height H centimetres of the piston at T seconds is given by the formula H=120sin pi T + 200
A)State the aplitude and period?
B)what are the maximum and minimum height of the piston ?
C)how many complete cycles does the piston make in 30mins?
The volume of air in the lungs can be modelled by a sinusoidal wave.
A) The volume of air in the lungs varies from 1000ML to 5000ML over a period of 6s. Determine an equation for the volume of air over time.
B)Use the equation to determine the amount of air in the lungs at
I answered all my other questions and these questions seems to be giving me grief haha(Tmi)
