| I'd like to find some good ways to create the 3D region by taking the region bounded by $y=x^4$ and $y=1$ and rotating it about the line $y=2$. |
| I find the font size in the suggestion bar too small to read. Can I increase it? Also, if I am giving a presentation to students, can I increase it so they can see it from where they are sitting when presented on the Smartboard? |
| At school, I am teaching on a Windows 7 using Mathematica 10.2.0 (soon to be updated to 10.3.1.0). I am using SmartBoard version 14.2.953.0. I cannot get the SmartBoard pen to draw on top of the Mathematica notebook. Is there a workaround for... |
| We have 12 iMacs in our computer lab at our college. They over five years old but we upgraded to Yosemite and added memory. Our students are having problems trying to print (to a black and white printer) their notebooks. Testing one students notebook... |
| I installed Mathematica 10 and also the Extra Packages. I think this installed Wolfram CDF player, but I don't see that in my Applications folder on my MacBook Pro. I can export to a standalone CDF file from Mathematica, but if I try to open a CDF... |
| Hi, I am using Mathematica 10.1.0.0 on my MacBook Pro (10.10.3). Also, I recently updated Command Line Tools (OS X 10.10). Here is the code that is causing a problem. Show[ ContourPlot3D[{x == 0, y == 0, z == 0}, {x, -3, 3}, {y,... |
| Hi, One of the greatest difficulties I have with Mathematica is pairing braces, brackets, and parentheses. I am constantly forgetting one and it is quite difficult to correct this type of mistake. On the Mac, I've learned about Ctrl+. and... |
| All the fonts in Worlfram Workbench are a bit too small for me to read. Is there a way to increase every font size in a simple manner? |
| Here is my effort to find the solution of $$\frac{dy}{dt}=\frac{2\sqrt{y}-2y}{t},\quad y(-1)=1$$ Note that this equation is in normal form, $y'=f(t,y)$, where $$f(t,y)=\frac{2\sqrt{y}-2y}{t}.$$ I believe this function $f(t,y)$ is continuous on... |
| I repeatedly get a response similar to the following: In[13]:= Clear[Derivative]; gensol = DSolve[y'[x] == (2 Sqrt[y[x]] - 2 y[x])/x, y[x], x] During evaluation of In[13]:= Solve::ifun: Inverse functions are being used by... |
