| Sep 18, 2016 at 20:10 | comment | added | Jens | What you want is probably this: eqn1=Simplify[lhs==k1^2,r>0]//Expand. The r^2 is eliminated automatically that way. | |
| Sep 18, 2016 at 18:27 | comment | added | MarkM | Didn't work. I removed my 'multiply by r^2' hack and got an r below the line on eqn12. | |
| Sep 18, 2016 at 18:09 | comment | added | Jens | I think that will lead back to what I did in my answer here. I.e., divide by f and apply the same tricks as above to get the first separation. | |
| Sep 18, 2016 at 17:56 | comment | added | MarkM | In a more general situation, where I don't play tricks by multiplying by r^2when creating eqn1, I'd like to be able to (say) put r, R, R', R'' ... etc on one side and all the equivalent [Theta]'s on the other. | |
| Sep 18, 2016 at 17:31 | comment | added | Jens | Can you elaborate on what you mean by "include"? I don't see where else they should appear. | |

| Sep 18, 2016 at 16:58 | comment | added | MarkM | That works very well for [CapitalTheta][] and R[], thanks! How do I include [Theta] and r? | |
