Every time heart beats, blood pressure first rises and then reduces as heart rests between beats. Maximum and minimum blood pressures are known as systolic and diastolic pressures, respectively. Blood pressure reading is written as systolic/diastolic. Reading of 120/80 is considered normal. Certain person's blood pressure is modeled by function:
p(t)=115+25*sin (160pi*t)
where p(t) is pressure in mmHg, at time t measured in minutes.
a) Determine the period of p
b) Determine number of heart beats per minute.
c) Graph function p
d) Compute blood pressure reading. How does compare to normal blood pressure?
