In the media today, there continues to be much discussion about how students in North America are moving away from the math, science, and engineering disciplines. It is an established fact that countries such as China, South Korea, and Taiwan graduate a much higher number of engineering students than those in North America. This is a cause for great concern in today’s highly complex world, and schools are attempting to solve the problem with math in a variety of ways, with varying success rates.

Hi,

I am kind of new with using maple, and I am hoping that someone can give me some help on nonlinear curve fitting.  I checked out the help topics, and I thought that I had put everything in correctly, as per the help file.  However when I try to do a fit to data, nothing is returned.  Here is what I have input:

Hi all, I'm not good at maple, so need a help from experts. I'm using Maple v.12. -part of the code- ... de2:= # Nonlinear DE is here # ics:= X(0) = 1, (D(X))(0) = 1; sol:= dsolve({de2, ics}, numeric, method = rkf45); (or sol := dsolve({de2, ics}, x(t), numeric, stiff = true, range = 0 .. 200);) Error, (in f) unable to store '1.0000000024691*{1.}^2+2000010000.' when datatype=float[8] -end of the code- As you see above, It's a simple process to solve DE. so most of the DE, like (1) below, is solved very well through the code. But my case is (2). I could see error msg as you see above.

Good day, I cannot run this maple, why?

I need help!

I'm trying to plot a sphere, and then shade-in the bottom one-third of it.  Is that possible?

Also, I then need to plot a sphere with 8 approximating disks.

Does anyone have any ideas of how to do these?
