Integration question involving cosh^-1???

Evaluate the integral (1/sqrt(x^2 - 5))dx on limits of 3 to 4, using the formula: integral of (1/sqrt(x^2 - a^2))dx.
Recall that this formula was found by using the substitution x = a cosh t, and observing that cosh^-1 (x/a) and ln(x + sqrt(x^2 − a^2) differ by a constant.
Help please?
