    Verify the hyperbolic identites

    Homework Statement verify these identities: 1) tanh^2 x + sech^2 x =1 2) sinh(x+y) = sinh cosh y + cosh x sinh y Homework Equations cosh2x - sinh2x = 1 sech2x + tanh2x = 1 coth2x - csch2x = 1 sinh (x ± y) = sinh x cosh y ± cosh x sinh y cosh (x ± y) = cosh x cosh y ± sinh x...
