The following integral evaluates to:

\[\int_0^1 \left(E(k)-\dfrac{\pi}{2}\right)\,\frac{dk}{k}=a+\dfrac{\pi}{b}+c\int_0^{\pi/4} \ln(\cos x)\,dx\]

where \(a\), \(b\) and \(c\) are integers. Find \(|a|+|b|+|c|\).

**Details and Assumptions:**

- \(E(k)\) is complete elliptic integral of the second kind.
