    Modelling Blood Pressure

    A personís blood pressure at time t (in seconds) is modelled by the function p = 100 + 18 sin 7t. How many heartbeats occur per minute?

    This is how I approached it:

    I found the maximum and minimum values for p. One heart beat would consist of the function reaching its maximum and minimum values once.

    Then, I found a period of a heart beat by dividing 2*pi by 7.

    So, to determine the number of heart beats per minute would I simple multiply 2*pi/7 by 60?

    one beat takes \frac{2\pi}{7} seconds ...
