Elizabeth wants to know the angle at which the sun
hits a tree in her backyard at 3 pm. She finds that
the length of the tree's shadow is 24 feet at 3 pm.
At the same time of day, her shadow is 6 feet 5
inches. If Elizabeth is 4 feet 8 inches tall, find the
height of the tree and hence the angle at which the
sunlight hits the tree. Round the angle to the
nearest degree.

Prove (a) cosh2(x) ā sinh2(x) = 1 and (b) 1 ā tanh 2(x) = sech 2(x). solution (a) cosh2(x) ā sinh2(x) = ex + eāx 2 2 ā 2 = e2x + 2 + eā2x 4 ā = 4 = . (b) we start with the identity proved in part (a): cosh2(x) ā sinh2(x) = 1. if we divide both sides by cosh2(x), we get 1 ā sinh2(x) cosh2(x) = 1 or 1 ā tanh 2(x) = .
