| Hi, I want to upload a basic sketch to ***Arduino Uno R3*** board. This is the sketch: int ON=500; int OFF=500; void setup() { pinMode(7,OUTPUT); } void loop() { ... |
| Hi, The code below don't work! f[x_] := x^2 + 2 x - 3 p = {{a, f[a]}} Animate[ Plot[f[x], {x, -2, 4}, Epilog -> Point[p]], {a, -2, 4}] But, If I replace the variable p with is evaluation, the code is OK. ... |
| In a simple plot like this; f[x_]:=(2x+3)/(3x-2) Plot[f[x],{x,-3,3}] I don't want to see the vertical asymptote. How can I tell the Plot function to do this? Thank you! Marcel. |
| I would like to encrypte a Mathematica document with a secret password. I don't know if Mathematica can do a thing like that... Marcel Pelletier |
| Hi, This is my code: In[1]:= f[x_] := x^2 In[2]:= g[a_, b_] := NIntegrate[f[x], {x, a, b}] In[3]:= g[1, 2] Out[3]= 2.33333 In[4]:= NSolve[g[1, b] == 3, b] During evaluation of In[4]:=... |
| So, since Mathematica 10, the axes on my plot are so thin that I have difficulties to see it. How can I make the axes more darker? Than you |
| Hi, I made a correction in the function "RisingTrannsitSetting". So I post the new library. Marcel. |
| Hi, A new function to the package: PhasesOfTheMoon[{y,m,d}] Marcel. |
| Hi, A new function (EquinoxesAndSolstices[year]) and a correction in the function RisingAndSetting. Marcel. |
