You may have better luck using something like Map to make a list of the images you want and then just export that list. The first example in the documentation on the AVI format shows the export of a list of images: ...
I think this depends on the class. Certainly, if I had had Mathematica available to me when I was taking Calculus I, I could easily have cheated my way through it.  I would not have had to work very hard and I would not have learned the concepts at...
So my next thought would be to check the video card / driver. Are you using an nvidia driver? If so, are you using the 319 driver? I've seen a number of issues with the 304 nvidia driver and have found that they are mostly fixed in the 319 driver.
Without seeing the definitions of f1 and f2, no-one is going to be able to say for sure what is going on. However, on many occasions, numerical round-off error has appeared systematic when I have worked on solving differential equations. For one...
Well, in linux, you can launch the front end with the command mathematica. I'm not entirely sure, but I think the command is the same on Mac (I always use the icon in that bar at the bottom) and I always just use the start menu item in Windows. If...
You're actually running into a number of items. First, Mathematica's default display setting shows 6 digits of precision. You can edit this by going to Edit->Preferences and then selecting the Advanced tab, then hitting the Option Inspector button....
You should directly contact info@wolfram.com or call 1-800-WOLFRAM and navigate to customer support Mon-Fri 8 am - 5 pm central.
Clear removes values and definitions from a symbol while ClearAll removes attributes, messages and any default options as well as values and definitions from a symbol. The * kind of has the same meaning it does on a unix terminal, meaning any set of...
The lightweight grid manager needs to use port 3737. That means that you need to be able to communicate with that port from the machine you wish to acquire additional kernels for. When I set this up on Windows 8.1,  I had to add a special rule to...
So DSolve can use Piecewise functions, e.g.:eqns = {y'[x] == Piecewise[{{-y[x], x >= 0}}, 0], y[5] == 10} DSolve[eqns, y[x], x]What's the definition of sol3 and what error message are your getting?
