I would think this should do it...

=COSH(A1)^2

If you are going to make it part of a longer calculation, then you might
want to enclose it in parentheses to make it clear what is going on....

=3*(COSH(A1)^2)+4

I need to use the funtion COSH squared or COSH ^2 in a cell to calculate an
answer. How can this be done?
