A patient's blood pressure can be expressed as:
where 
is the blood pressure measured at time t.
[Pressure is measured in mmHg (millimeter of mercury) and is a unit for measuring blood pressure in medicine; one millimeter of mercury corresponds to 133.322 pascals.]
Determine the amplitude and period of the function p.
Determine the maximum blood pressure that can be measured and calculate when it occurs.
Sketch the graph p (t).
Find the first time the device detects 110 mmHg.
