Select the simplification that accurately explains the following statement.
37 = 73
OA (73) = 73.73.73 = 7. (1++ 3) = 7.5 = 7 -1 = 7
OB (73) = 73.73.75 = 73-}.} = 7: = 71 = 7
oc (72) = 75.78.75 = 7.74= 3-5-7 = 1.7 = 7
D. (-) = 77.73.73 = 7++ = 78 = 71 = 7

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) = .
