Apply the Taylor Formula

= \frac{2}{e ^{2} - 1} + \frac{\frac{d}{d x} ( \frac{2 x}{e ^{2 x^{2}} - 1} ) ( 1 )}{1 !} (x - 1) + \frac{\frac{d ^{2}}{d x ^{2}} ( \frac{2 x}{e ^{2 x^{2}} - 1} ) ( 1 )}{2 !} (x - 1)^{2} + \frac{\frac{d ^{3}}{d x ^{3}} ( \frac{2 x}{e ^{2 x^{2}} - 1} ) ( 1 )}{3 !} (x - 1)^{3} + \dots
