I really got lost here. I am trying to figure out x where X1 is equal to zero.

Here is the file. See what is the issue?

plot it first to see where to look, then give an initial value for x in keeping with where the nearest point to your desired value is.

The function is never equal to zero.

well I need to find x and assume the function equal to zero

so that what I believe ; but could you please explain why it should not be zero

If x is real then cosh(x) has a minimum value of 1, when x=0. The function cosh(x) is never equal to zero for real x. If x is allowed to be complex you have a solution, but not if x must be real.
