| For the function f[x] defined in [1] below, evaluation [5] below is inconsistent with evaluations [2] to [4] below. Note the change in sign preceding y in evaluation [5] below. In[1]:= f[x_] := DiracDelta'[x - 1] In[2]:=... |
| Why do I get the same results from each of the first pair below, but different results from each of the second and third pairs below? How do I rewrite In[653] and In[655] to get the correct result? ------------------------ In[657]:=... |
| Mariusz: Thanks for the reply. Your suggestion to use ListLinePlot seems to have the added benefit that it evaluates much faster than the Plot function. |
| I'm running Mathematica 11 Home Edition on 64-bit Ubuntu 16.04 LTS on an Intel i5 processor. I'm pretty sure I'm still running the old version as it remembered all of my recent files and didn't ask for the license key the first time I launched... |
| Sander: Thanks for taking the time to review and respond to my question, but I no longer need help at this time since encapsulation with $N()$ provides a satisfactory workaround for the problem. If you're interested in the general topic of prime... |
| I've derived formulas for the Riemann zeta function $\zeta(s)$ and the first-order derivative $\zeta'(s)$ which are illustrated on pages 11.3 and 11.4 of the following website. I'm now attempting to understand and optimize two formulas which I've... |
| Christian: Thanks for the response, but not exactly. Assuming I have a single-dimensional list called data, I want to index into this list similar to one of the following: data[[PrimePi[x]]] data[[Floor[x]]] ... |
| Daman: Thanks for the clarification. My Raspberry Pi SD card image got corrupted to the point of being unusable a couple of days ago (which has happened several times before), so I'm currently using the trial version of Mathematica 11 on the PC. I'm... |
| Daniel: Thanks for the reference. I reviewed an online copy of this reference at the beginning of the year. Could you please point me to a reference with respect to the objectives of the forum? I can't seem to find them anywhere. |
| Is there a built-in function in Mathematica for the greatest square-free divisor of an integer (which I believe is also called the radical or square-free kernel of an integer). I know I can write my own function, but it seems to me there should be a... |
