The integral of sqrt(x-1)/sqrt(x) can be effectively solved using the substitution x = cosh²(u), which simplifies the expression significantly. This approach leverages hyperbolic functions to transform the integral into a more manageable form. The initial substitution of x = sinh²(u) may complicate the process, as it introduces additional complexity without yielding a straightforward solution. Therefore, using x = cosh²(u) is the recommended method for solving this integral.
