MHB Using the General Series Command on Nspire CX CAS

AI Thread Summary
The discussion focuses on using the generalized series command on the Nspire CX CAS to find sums of series without specified domains. Users are advised to select "Sum" from the main menu and utilize the sum template for input. An example series, $\frac{1}{5}+\frac{1}{7}+\frac{1}{9}+...$, can be entered as $\sum_{n=5}^{\infty}{\frac{1}{n}}$, but the calculator will indicate that this series is divergent. Understanding how to input series correctly is crucial for accurate calculations. Proper usage of the generalized series command is essential for handling complex series in the Nspire CX CAS.

Can't you just choose "Sum" from the main menu and fill in the sum template?
 
what if I am given a series in the form of $\frac{1}{5}+\frac{1}{7}+\frac{1}{9}+...$ how would i put that into the calculator?

You'd put in the template $\displaystyle \begin{align*} \sum_{n=5}^{\infty}{\frac{1}{n}} \end{align*}$, but it will tell you that this particular series is divergent.
