… ►The first positive zero of $f(x)$ lies in the interval $(\pi ,\frac{3}{2}\pi )$; see Figure 4.15.3. … ►All zeros of $f$ in the original interval $[a,b]$ can be computed to any predetermined accuracy. … ►There is no guaranteed convergence: the first approximation $x_2$ may be outside $[x_0,x_1]$. … ►Consider $x=20$ and $j=19$. We have $p^{\prime }(20)=19!$ and $a_{19}=1+2+\mathrm{\cdots }+20=210$. …

§22.17 Moduli Outside the Interval [0,1]

… ►Jacobian elliptic functions with real moduli in the intervals $(-\mathrm{\infty },0)$ and $(1,\mathrm{\infty })$, or with purely imaginary moduli are related to functions with moduli in the interval $[0,1]$ by the following formulas. … ►When $z$ is fixed each of the twelve Jacobian elliptic functions is a meromorphic function of $k^2$. …In particular, the Landen transformations in §§22.7(i) and 22.7(ii) are valid for all complex values of $k$, irrespective of which values of $\sqrt{k}$ and $k^{\prime }=\sqrt{1-k^2}$ are chosen—as long as they are used consistently. For proofs of these results and further information see Walker (2003).
