    Having another problem.

    Find the definite integral.

    \int_1^4 \frac{1}{x\sqrt{16x^2-5}}dx

    I tried multiplying the integral by 5, and putting a 5 in the denominator, and working that into the radical, but I still can't get the denominator to fit the equation of the arcsec.

    Thanks for taking a look!
