| Dear: I have tried to use the example in Pos 7387 from Schaum's Outline of Mathematica (example 9.18). Unfortunatelly it did not work. Based on tips from the Community I have tyried to use ?NumericQ when defining Integrate or Assumptons->.... |
| [mcode]In[422]:= x[y_] = Sqrt[16 - y^2]; A[h_] = 2 NIntegrate[x[y], {y, 0, h}]; In[421]:= FindRoot[A[h], {h, 1.6}] Out[421]= {h -> 1.6} In[408]:= FindRoot[2 NIntegrate[Sqrt[16 - y^2], {y, 0, h}] == 4 \[Pi], {h, 1.6}] Out[408]= {h ->... |
| Dear: The commands bellow should result in A[4]= 8Pi but as you can see the result was undefined. Should you help me?In[294]:= x[y_] = Sqrt[16 - y^2]; A[h_] = 2 Integrate[x[y], {y, 0, h}]; A[4] Out[293]= UndefinedThanks, Ana |
| Dear : I would like to copy a text from the Documentation Center but I just may copy in the MathML or LaTex Formats. How could I convert one of these formats to Word 2010? thanks, Ana |
| Thank you |
| Dear, Can I create directly a polynomial division in the Standard Form without using the followings commands: FractionBox or StandardForm? I have tried to find out the horizontal bar to make division but I couldn't find. Thank you Ana |
| Thank you |
| I was talking about texts from the Documentation Center not about Notebook. I have read in Mathematica that I just can copy the pages as MathML or LaTex format. So I said that I do not know how to work in these formats and I would like to know... |
| I have read in a book that the control WorkingPrecision default is 16. Nevertheless when I have used the FindRoot command as showed below with WorkingPrecision ->16 and without WorkingPrecision control I found different answers. I would like to know... |
| Version 9.0.0. I find out the cause of the error. I was using Skydrive and the command ContourPlot3D was not accepting h and g as the functions. I had to copy all the expressions and replace h and g. Now I am working out of the skydrive and... |
