The following corrections and other changes have been made in the DLMF, and are pending for the Handbook of Mathematical Functions. The Editors thank the users who have contributed to the accuracy of the DLMF Project by submitting reports of possible errors. For confirmed errors, the Editors have made the corrections listed here.

$$x\left(t\right)=a\mathrm{cn}\left(t\sqrt{1+2\eta},k\right)$$ |
Originally the term $\sqrt{1+2\eta}$ was given incorrectly as $\sqrt{1+\eta}$ in this equation and in the line above. Additionally, for improved clarity, the modulus $k=1/\sqrt{2+{\eta}^{-1}}$ has been defined in the line above.
Reported 2014-05-02 by Svante Janson.
Two corrections have been made in this paragraph. First, the correct range of the initial displacement $a$ is $$. Previously it was $\sqrt{1/\beta}\le \left|a\right|\le \sqrt{2/\beta}$. Second, the correct period of the oscillations is $2K\left(k\right)/\sqrt{\eta}$. Previously it was given incorrectly as $4K\left(k\right)/\sqrt{\eta}$.

In the original equation the prefactor of the above 3j symbol read ${\left(-1\right)}^{-{j}_{2}+{j}_{3}+{m}_{3}}$. It is now replaced by its correct value ${\left(-1\right)}^{{j}_{1}-{j}_{2}-{m}_{3}}$.

Originally a minus sign was missing in the entries for $\mathrm{cd}u$ and $\mathrm{dc}u$ in the second column (headed $z+K+i{K}^{\prime}$). The correct entries are $-{k}^{-1}\mathrm{ns}z$ and $-k\mathrm{sn}z$. Note: These entries appear online but not in the published print edition. More specifically, Table 22.4.3 in the published print edition is restricted to the three Jacobian elliptic functions $\mathrm{sn},\mathrm{cn},\mathrm{dn}$, whereas Table 22.4.3 covers all 12 Jacobian elliptic functions.

The entry for $\mathrm{sn}z$ at $z=\frac{3}{2}\left(K+i{K}^{\prime}\right)$ has been corrected. The correct entry is $\left(1+i\right)\left({\left(1+{k}^{\prime}\right)}^{1/2}-i{\left(1-{k}^{\prime}\right)}^{1/2}\right)/\left(2{k}^{1/2}\right)$. Originally the terms ${\left(1+{k}^{\prime}\right)}^{1/2}$ and ${\left(1-{k}^{\prime}\right)}^{1/2}$ were given incorrectly as ${\left(1+k\right)}^{1/2}$ and ${\left(1-k\right)}^{1/2}$.
Similarly, the entry for $\mathrm{dn}z$ at $z=\frac{3}{2}\left(K+i{K}^{\prime}\right)$ has been corrected. The correct entry is $\left(-1+i\right)k^{\prime}{}^{1/2}\left({\left(1+k\right)}^{1/2}+i{\left(1-k\right)}^{1/2}\right)/2$. Originally the terms ${\left(1+k\right)}^{1/2}$ and ${\left(1-k\right)}^{1/2}$ were given incorrectly as ${\left(1+{k}^{\prime}\right)}^{1/2}$ and ${\left(1-{k}^{\prime}\right)}^{1/2}$
