You are asked to determine the estimated number of car accidents per month at a specific intersection. Your report needs to be on your supervisor's desk the next morning. Since it is an estimate, your supervisor asked for an estimate with 98% confidence. In response to this assignment, you randomly selected a sample of 16 months over the last few years and compiled data on the number of car accidents that occurred during each of these months. The mean number of car accidents in these months was 42 per month with a sample standard deviation of 9 per month. What estimate will your report indicate

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) = .
