Two people decide to find the height of an ancient tree. One person stands a certain distance from the base of the tree and measures the angle of elevation from her position to the top of the tree to be 65º. If the second person stands 25 feet farther away from the first person and the tree measures the angle of elevation to the top of the tree and measures the angle of elevation to the top of the tree to be 44º, how tall is the ancient tree

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) = .
