Hi I need help on the following questions: 1) Express sinh(x+y) in terms of sinh(x), sinh(y), cosh(x), cosh(y) 2) Given cosh find values of sinh(u) This is what i have done: made so sinh(u) = 1.89. What is wrong?? P.S

this is what i have done, someone tell me if this is a correct way of doing it my answer is slighlty difference to the book's answers of .
