At rest, the human heart beats once every second. At the strongest part of the
beat, a person's blood pressure peaks at 120mmHg. At the most relaxed part
of the beat, a person's blood pressure drops to 80mmHg. Supposing that t = 0
corresponds to the peak of the beat, write down a trigonometric function that
captures this behavior.

since it's a max at t=0, that indicates a cosine function
The period is 1, so we are looking at cos(2pi*t)
max is 120, min is 80, so amplitude is 20, and oscillates around h=100, and our function is
f(t) = 100 + 20cos(2pi*t)
