\[-\frac1{\frac{\pi}{4}} \cdot \log \left(\frac{e^{\frac{\pi}{4} \cdot f} + e^{-\frac{\pi}{4} \cdot f}}{e^{\frac{\pi}{4} \cdot f} - e^{-\frac{\pi}{4} \cdot f}}\right)\]
Applied taylor 1.6
\[\leadsto -\frac1{\frac{\pi}{4}} \cdot \log \left(\frac{e^{\frac{\pi}{4} \cdot f} + e^{-\frac{\pi}{4} \cdot f}}{\frac{1}{2} \cdot \left(\pi \cdot f\right) + \left(\frac{1}{192} \cdot \left({\pi}^{3} \cdot {f}^{3}\right) + \frac{1}{61440} \cdot \left({\pi}^{5} \cdot {f}^{5}\right)\right)}\right)\]
Taylor expanded around 0 1.6
