Annie wants to arrange her science, English, and math text books in a row on a shelf. Which tree diagram best shows the sample space of all the possible ways to arrange the three books in a row on a shelf, where S is science, E is English, and M is math?
A tree diagram is shown. The lines branch out to S, E, and M. In the first row, the lines branch out from S to E to M and from S to M to E. In the second row, the lines branch out from E to S to M and from E to M to S. In the last row, the lines branch out from M to E to S and from M to S to E.

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) = .
