6) Neda, who is 5.45 feet tall, is taking a picture of a tall monument and wonders how tall it is. Neda is standing 689 feet from the base of the monument, such that the end of her shadow meets the end of the monument's shadow. If Neda's shadow is 6.75 feet long, find the height of the monument to the nearest foot.

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) = .
