The example of computing \(\Sigma_{k=1}^{100}\sqrt{k}\) is actually an example of calculating \(\Sigma_{k=0}^{100}\sqrt{k}\). The likelihood that the reader will be misled is potentially increased by the fact that the result is, of course, the same.

Also, I believe that the documentation should warn the reader about all operations, like \(\Sigma\) and \(\Pi\), that clear or otherwise invalidate the stack. The warning should be similar to the one provided for f'(x), preferably improved to not assume that the stack size is 4. It also might be helpful to change the worked \(\Sigma\) example to \(\Sigma_{k=1}^{100}\sqrt{k} + \Sigma_{k=201}^{300}\sqrt{k}\). or something similar, as a way of conveying to the reader that the stack cannot be relied on to hold intermediate results.

Thanks for reporting. I'll look into that later.

Edit:
Ok, although the summation example you quote may be seen as a little test for the reader, I will change the start value to 100.001 to avoid that challenge.
And the documentation stubbornly repeats "... fills all stack levels with x before calling the routine specified." for f', f", SLV, \(\Pi\), \(\Sigma\), and Integrate. So I think I've fulfilled my duty there, haven't I?
