comment Discontinuous Forcing for a Cancer Model — Issues with v9 NDSolve
The parameter lambda2 in the definition of g seems to be written somewhat incorrectly. It appeared in blue, though lambda2 has already been assigned to zero few lines above. After I have copy-pasted the word lambda2 from its first appearance in the very first code line into the line where g is defined, as well as fixed options according to Mr. Wizard's advice all error messages disappeared.

comment Replace symbols with values without evaluation
@Tyilo No, the up- and downvotes are no matter for me. I just discuss the essence as I understand it. Have fun.

comment FullSimplify giving unexpected result
It seems me that @eldo rises here one of the Mma mysteries. I also have several times met situations when Simplify or FullSimplify with worked "in the direction" opposite to that indicated by the ComplexityFunction.

comment How can I get the function of a plotted trajectory?
There is also FindFit that typically can do the job within Mma without attractind additional programs.

comment Attaching functions to movable locators
It should be straightforward, if you use the LocatorPane or Manipulate with the Locator as the Control. You just fix the points p1, p2,... as the locator coordinates and the same values give for the points of your present plot. I cannot help more without the code of your present attempt. This is also a general rule here: that is to show what you have already done in the direction.

comment Getting long complex-valued integrals when simpler real-valued expressions exist
@user19228 I see. I tried your integral and saw that this condition makes no harm (and no action at all). In fact this condition is natural to use in Simplify or FullSimplify, which you might apply to the result of the integration, rather than in the Integrate.

The condition 0<a<Sin[theta] with the statement that ais a constant sounds strange.

comment How to modify the elements of a list in a loop?
@user5693 Well, what I did is essentially the same you have written in your example, but yielding the output. The possible source of misunderstanding is (as it has been mentioned by Mr. Wizard) that you gave no examples of your data, parameters and expected output. In particular, I assumed rx, t1 and t2 to be vectors. Are they not? Then your result will, of course, differ from expected one.

comment How to select the text on the button?
@Öskå Of course not. Then you select/copy the whole button, open a notepad, paste the button there and select www this time from the notepad. Or even better: you just type "www" in whatever place you like. Done. The question is, therefore, what is the ultimate aim of such a selection. But that I have already written.

comment How to select the text on the button?
@Öskå The question is, what is the ultimate aim of it. That is, what will the OP do afterwards. I can easily copy/paste the whole button (which is this case has the appearance of the text), including pasting it into Mma with and into a Word document without the button functionality.
