## Homework Statement

(1 / x * sqrt(4x^2 - 1))dx

## Homework Equations

done by parts/trig?

## The Attempt at a Solution

1 = c

2x = b

sqrt(4x^2 - 1) = a

sin(theta) = 2x

sin(theta) / 2 = x

-(1/2)*cos(theta) d(theta) = dx

cos(theta) = -2*sqrt(4x^2 - 1)

I am not sure what to do about the x?

Can I just replace it all now?
