A rancher has a square cow pen with side length 2. He decides to change the shape of the pen while still using the
same amount of fencing materials. The equation (-+ + 10) (0 β 10) = 300 represents the relationship of the new side
lengths in feet) of the pen and its area (in square feet).
Find the original side length in feet) of the square pen. Show your reasoning.

Prove (a) cosh2(x) β sinh2(x) = 1 and (b) 1 β tanh 2(x) = sech 2(x). solution (a) cosh2(x) β sinh2(x) = ex + eβx 2 2 β 2 = e2x + 2 + eβ2x 4 β = 4 = . (b) we start with the identity proved in part (a): cosh2(x) β sinh2(x) = 1. if we divide both sides by cosh2(x), we get 1 β sinh2(x) cosh2(x) = 1 or 1 β tanh 2(x) = .
