| Thanks,Nasser. I agree, strings are not the answer. I should have been more explicit: I want to pass a variable in a function. Here is something that might work: In[77]:= Remove[test1]; SetAttributes[test1,HoldAllComplete]; ... |
| Thanks, Sean. Using the notations package prompted the question. All that talk of boxes is beyond me, for now. I'll just hijack the >>> operator; the unused operators require complicated typing and don't convey the sense of the operation. |
| Thanks, Sander. My first vote! This might be the final post. Some rigorous testing needs to be done, so if you can find an error, please respond. The last post was in error about the correct format. Here is the way it looks now: ... |
| This is a naive string manipulation, but it works OK for positive integer powers. newTerm[a_,b_]:=ToExpression[(a//ToString) "ยข" (b//ToString)] ... |
| The equation of the sphere is easy: \[Rho] == 2 The equation of the cylinder is: \[Rho] == 2 Cos[\[Phi]] Csc[\[Theta]] See SphericalPlot3D for information about rho, theta, and phi. Theta and phi can change from one text to... |
| Hi Vasily, Edit: removed post. Eric |
| Hi Fabio, I've run into this problem, too. It turns out that the forum software interprets anything between two asterisks as italics. In fact, anything between two sets of double asterisks is bold and anything between two sets of triple... |
| Thanks Henrik, That is a new notation for me. So the `[a_==b_]` automatically takes the stuff to the left of the double slashes just like crossMultiply did. This opens a whole new area to explore. Eric |
| In regard to David Keith's fromPolarRule, note that ArcTan[y, x] should read ArcTan[x, y]. |
| Please see the attached notebook. I wasn't able to get the Pi^2 under the radical, though. |
