Prove (a) cosh2(x) â sinh2(x) = 1 and (b) 1 â tanh 2(x) = sech 2(x). solution (a) cosh2(x) â sinh2(x) = ex + eâx 2 2 â 2 = e2x + 2 + eâ2x 4 â = 4 = . (b) we start with the identity proved in part (a): cosh2(x) â sinh2(x) = 1. if we divide both sides by cosh2(x), we get 1 â sinh2(x) cosh2(x) = 1 or 1 â tanh 2(x) = .
