1. The problem statement, all variables and given/known data

Question is:

and

2. Relevant equations

Now from what i can recall the formula for sin(A+B) = sinAcosB+sinbcosA

so same goes for hyperbolic function i suppose?

sinh(2x+x) = sinh2xcoshx+cosh2xsinx

(2sinhxcoshx)coshx + (cos^2hx+sinh^2hx)sinx :/ am i on the right track... what confuses me are the identities of cosh2x .

EDIT: WOULD I USE COSH2X= 1+2SINH^2X?

CONFUSED :(

Thanks for your input in advance!
