| I got two responses quickly, and one of them furnishes partial answer, First I need to generate the data, which was furnished by Rohit Namjoshi Then I found how to convert the spherical coordinate data to Cartesian coordinates so that I can plot... |
| It works fine. Thanks for prompt and accurate reply. |
| I think I have found the solution. The following three operations In[24]:= (*Exercise in table manipulation*) xt = Table[{NSolve[x^2 - .001 i == 0 && x > 0]}, {i, 8}]; In[25]:= { {xt1 = xt /. {{Rule[a_, b_]}} :> b;}, {\[Placeholder]} } ... |
| Fantastic, it worked! I got: In[7]:= ssReal = Cases[{\[Rho], \[Theta]} /. ss, {_Real, _Real}] Out[7]= {{0.152974, 0.785684}, {0.417435, -0.617471}} Thank you and others who responded to my problem. |
| I am evaluating the following: N[Gamma[3/2] PolyLog[3/2, -Exp[3]]] I got the answer -3.97699 + 1.26361*10^-16 I the real part is correct, but the answer contains a very small imaginary part, probably due to rounding errors. Has anyone encountered... |
