Onyango observed a hawk exactly overhead at the same time as Kamau observed it at an
angle of elevation of 50°. If Onyango and Kamau were 25m apart on a level ground, how
high was the hawk above the ground, given that Kamau's eye level was 172cm above the
ground?

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) = .
