Suppose you think the average driving speed on Interstate 94 is 75 mph. Your friend thinks that the average is really greater than 75 mph. To test this you take a sample of 36 people and ask them how fast they drive on Interstate 94. After collecting your sample, you calculate that the mean is 78 mph with a standard deviation of 9 mph and want to find if your friend is right with alpha

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) = .
