Series values along the real axis

Plots of the imaginary part of the first terms of the Taylor series of along the real axis. As increases, the curves vary from red to violet. Because the series misses even terms, the curves for the pairs and , and , and coincide.

Plots of the first terms of the Taylor series of along the real axis. As increases, the curves vary from red to violet. The radius of convergence of the series is 1.

Series values in the complex plane

Curves connecting points and by summing successively terms of the Taylor series. The number of terms summed increases from for the lower plane to for the upper plane.

Zeros of the series in the complex plane

Curves of vanishing real part (red) and vanishing imaginary part (blue) of the first 10 terms of the Taylor series of in the .

Contour plot of the argument of the Padé approximant of the function in the . The coloring is cyclical from red () to red ().
