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?
