if sinhx=-3/4 Find the values of the other hyperbolic functions. SHOW ALL WORK! Hint* use the identity: cosh^2-sinh^2. PLEASE EXPLAIN. I really dont understand...thank you! Solution cosh^2x= 1+ (9/16)= 25/16 cosh^2?-sinh^2?=1 => coshx= 5/4 tanhx= sinhx/coshx= 5/-3 cothx=-3/5 sechx=4/5 cosechx=-4/3.
