Consider the experiment, called the birthday problem , where our task is to determine the probability that in a group of people of a certain size there are at least two people who have the same birthday (the same month and day of month). suppose there is a room with 9 people in it, find the probability that at least two people have the same birthday. ignore leap years; assume each year has 365 days.

Prove (a) cosh2(x) − sinh2(x) = 1 and (b) 1 − tanh 2(x) = sech 2(x). solution (a) cosh2(x) − sinh2(x) = ex + e−x 2 2 − 2 = e2x + 2 + e−2x 4 − = 4 = . (b) we start with the identity proved in part (a): cosh2(x) − sinh2(x) = 1. if we divide both sides by cosh2(x), we get 1 − sinh2(x) cosh2(x) = 1 or 1 − tanh 2(x) = .
