 8h comment Manipulation of InterpolatingFunction If ifun is your interpolating function, you could for example write Sqrt[ifun[#]] &@t to get Q[t] and Sqrt[ifun[#]] &'@t to get Q'[t]. 14h comment Selecting expressions from a sequence that are not subexpressions of earlier elements Print[Unevaluated[1+1]] prints 1+1 but if we do for example expr={Unevaluated[1+1]}, Print[First@expr] prints as Unevaluated[1+1]. I think this is the problem, but I haven't got a solution. 1d awarded list-manipulation 1d answered Selecting expressions from a sequence that are not subexpressions of earlier elements 1d answered How to replace an element in a list based on the value of the next element? 1d comment Prime factor counting function Yes you could, because I guess it just means Length[PrimeOmega]==3 :P 2d comment How do I plot a plane pi/6 along with its path? Perhaps you are looking for Translate. 2d revised How do I plot a plane pi/6 along with its path? added 71 characters in body; edited title 2d comment How to map an image to get an illusion of 3D Much better! Very nice. 2d answered Pure function inside another pure function Dec6 comment How to map an image to get an illusion of 3D What are we looking at? How does it relate to what we see in the video? Dec6 comment How to map an image to get an illusion of 3D Neat presentation about this type (I think) of projection: facultyfp.salisbury.edu/despickler/personal/Resources/… Dec6 awarded Nice Answer Dec6 comment Make a differentiable smooth sawtooth waveform Plot[(2/Pi) Sum[(-1)^k Sin[2 Pi k t]/k, {k, 100}], {t, 0, 3}] will show Gibbs phenomenon for example, methinks. Dec6 revised Make a differentiable smooth sawtooth waveform added 21 characters in body Dec6 comment Make a differentiable smooth sawtooth waveform @ybeltukov Nice! I lifted it into the answer to make the answer more useful for future visitors. Dec6 revised Make a differentiable smooth sawtooth waveform added 265 characters in body Dec6 comment Make a differentiable smooth sawtooth waveform @ybeltukov I did not see that comment, thank you. I had never heard of Gibbs phenomenon before, however I observed it when I plotted the function for a smaller range of k, but I thought it died out with higher ones. I will update the post accordingly. Dec6 answered Make a differentiable smooth sawtooth waveform Dec5 comment 2d expression evaluated in 1d plot @JohnK I see, then I support bill's solution or it would also work to set y = some value and then Evaluate[AlphaXParam] as x does not have a value.
