Hyperbolic functions :(((
Question is:
and
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!
