Trig simplification help.
Express sinh(x)2cosh(x) as a sum of multiples of functions of the form cosh(nx).
(To explain by example what you should do: if the question had asked about sinh(x)4, the correct answer would be cosh(4x)/8−cosh(2x)/2+3/8.)
I have tried using maple to help me but am unclear how to tell it to.
any pointers in the right direction would be gratefully appreciated.
thanks.

thanks.
sinh^2(x)cosh(x) = (cosh^2x-1)cosh(x) = cosh^3(x) - cosh(x)
Sorry i should have put down what i have done already, i have done that but failed to see how it help.
Got it, thanks a lot for your help.
