I've been told the following expression can be manipulated into a product of squared terms.
(16*K/R)*cosh(y/2) + 2*(K^2)*cosh(y) - (16*K/R) - 2*(K^2)
(16*K/R)*[cosh(y/2) - 1] + 2*(K^2)*[cosh(y) - 1]
In order to do this, I've been told there should be an intermediate step,
(A/B + 1)*B
where B is a product of squared terms, and the expression inside the parentheses can itself be manipulated into a squared term.
Tried using some double/half angle substitutions, the exponential forms of sinh and cosh, etc. Nothing has clicked yet.
Does anyone else see how this can be done? Thanks.
