In a certain individual the resting diastolic pressure at time t is given by B(t)= 80+7sin((pi)(t)/(12)) where t is measured in hours since midnight and B(t) in mmHg (millimeters of mercury). Find this person's pressure at 6:00 am, 10:30 am, noon, and 8:00 pm.
What have you done so far?
e.g. at 10:30 am what is the value of t
did you sub that into the equation and evaluate it?
