## Best book resource for Maple 11?...

Asked by:
I am a new Maple user and I would like a good reference book for Maple 11, specifically one that is geared towards first-timers like myself. All of the Maple books I have seen are quite outdated and they would certainly not discuss the many new features of Maple 11. Thanks!

## Computational Limits Of The Combinat Package / Map...

Asked by:
Recently I tried to verify or expand on a recent biological statement that I read. It had to deal with 50 billion neurons each having about 10 thousand different connections each. After trying to discover the number of operands in the combination of 50 billion things chosen 10 thousand at a time, using the choose command, maple basically crashed. Approximately, what are the computational limits of maple in general, and combinat commands in particular ? For example, what is the biggest integer one can take the factorial of ? v/r,

## Limits of series...

Asked by:
Hey, I'm new to Maple (using both Maple 10 and 11), using it in my Calculus 2 class. I wanted to know if there is a way to find the limit of an infinite series, such as: sum((Pi+3*cos(x))/x, x = 1 .. infinity) If I can do it with Maple it will save me hours of work. Thanks, Evan

## Gauss elimination in Maple...

Asked by:
Hello, Given a system of differential equations as: C*V = O; where O is a null matrix and C is a 3X3 matrix as follows: Row 1: [rho*(alpha*I+omega*U*I), rho*U', alpha*I] Row 2: [0, rho*(alpha*I+omega*U*I), d/dy] Row 3: [alpha*I, d/dy, M^2*(alpha*I+omega*U*I)] The prime in Row 1 denotes differentiation with respect to y, and I is the unit imaginary number, d/dy is a differential operator. The vector V is given by: V = [u; v; w]; How do I use Maple to do a Gauss Elimination on the coefficient matrix which will give me separate equations for each of u, v and w. Or to be more specific, how do I represent the differential operator d/dy in a matrix

## Maple11 in Microsoft Virtual PC 2007...

Asked by:
Has anyone tried installing Maple within WinXP installed as on OS in Microsoft's Virtual PC 2007 running in Vista? It seems like it should run just the same as it would in normal WinXP. I've run Win98 in the Virtual PC 2005 running on WinXP Professional with no problems. This would allow Maple to run on the same system as Vista, even though it wouldn't make use of anything relating to additional RAM, additional CPU's, or whatever. Flipping between the two is very easy and it's even possible to share files between the native OS and virtual - at least with Virtual PC 2005 in case one wanted to do something with Maple output files within a program running on Vista.

## why am i getting an empty plot?...

Asked by:
I am solving and plotting mechanical spring vibration problems, and I keep getting an empty plot for this equation: y''+4y=2cos2t, y(0)=0,y'(0)=0. Here is how I entered it. Any help would be greatly appreciated. Thanks. e2:=(diff(y(t), t, t))+4*y(t) = 4*cos*t; s2:=dsolve([e2, y(0) = 0, (D(y))(0) = 0]); r2; rhs(s2); plot(r2, t = 0 .. 10); Error, empty plot

## Shading...

Asked by:
Hello all, I'm having a lot of trouble using the shading function. I'm trying to shade a circle a particular color but there is always an error. I found this website but I didn't figure out how to do it myself: http://www.indiana.edu/~statmath/math/maple/plotting/index.html I'm making a picture of a cartoon and my plots are all finished but the shading part is throwing me off; when I put in filled=true instead of filling the circle it makes a box the size of the radius on top of the circle. Can anyone help me?
