SUMMARY
The integral of the function 1/sqrt(x^2 - 1) can be expressed as arccosh(x), which can be proven using logarithmic functions. Specifically, the integral can be rewritten in the form of Ln(x + sqrt(x^2 - 1)). The discussion emphasizes the use of trigonometric substitution, particularly x = sec(theta), to simplify the integral. This method effectively demonstrates the relationship between hyperbolic functions and logarithmic expressions.
