| Hi Joseph, Try using HoldForm instead of Hold. "HoldForm[expr] prints as the expression expr, with expr maintained in an unevaluated form." In[208]:= y=x^2 Out[208]= x^2 In[216]:= y/.x->HoldForm[2] Out[216]= 2^2 Eric |
| Hi Konrad, Although the actions you are asking for would seem to be elementary, they can be hard to do when Mathematica is automatically evaluating every answer. For example, trying to divide both numerator and denominator by k1 will not do... |
| None of the great apes that have learned sign language have ever asked a question. Where would we be if we couldn't ask questions? That makes us fundamentally different from the apes. So what is the unknown intelligence or ability in the series ... |
| Here are three grids of external saturation vs internal saturation. In the RED grid, I see only a faint contrast throughout and nothing in the first three columns. In the GREEN grid, I see everything but the first column and good contrast. ... |
| Hi Mario, I've used the original dimensions of the platform because I don't know what your base is. I've also changed the rotation from radians to degrees. So, here is the interpolation function: splinedMotionPlan[motionPlan_, ... |
| Hi Yohann, When you are defining a function, the arguments have to be patterns. So, try this: a[f_, d_] := f (1 - E^(-d f)) Then look at the help for `Limit`. Some searching will reveal the use of Assumptions. In[5]:=... |
| Hi Mario, Did you use something like: `ExportMotionPlan[motionPlan,legoffsets_: -{0.17035,0.17035,0.17035,0.17035,0.17035,0.17035}]`? The legoffsets_:{...} idiom is only used in the definition of the function. When you call the function,... |
| Sure, why bother to test if HoldForm is needed or not? It's like going to the grocery store to buy a bag of chips and the salesclerk puts the bag of chips in a plastic bag. No thinking required. |
| How about full touch-screen functionality for notebooks? My new notebook computer has both touch screen and keyboard. I also have a wrist mouse problem, so I'm using the touch screen whenever possible. Normal touch screen functions like scroll... |
