A person’s resting blood pressure is 116 over 88. This means that the blood pressure oscillates
between a maximum of 116 and a minimum of 88. The person’s resting heart rate is 60 beats per minute.
Let P represent the blood pressure and t represent the time in seconds.
Write the equation for the blood pressure P as a function of time t seconds.
~~~~~~~~~~~~~~~~~~~~~~~
Mid-line is a = = 102.
The amplitude is A = = 14.
The period is T = = 1 second.
The cosine function is
P(t) = = 102 + 14*cos(6.28*t),
where t is the time in seconds.
