Solution of 1 equation with 2 unknown variables

How to find the solution of the equation using MATLAB?

[ In words, cos hyperbolic of x divided by cos hyperbolic of y is equal to 1 divided by 2 ]

A single equation with two variable can have an infinite number of solutions. You need to fix atleast one value. For example

y = 1.5;
x = acosh(cosh(y)*1/2)

In this case you have an expression for the solution of 'x' in term of 'y'. In general case, you can use fzero() or fsolve()

y = 1.5;
fzero(@(x) cosh(x)/cosh(y)-1/2, rand())
