Undefined versus Infinite result...

All:

Sometimes when I integrate through an infinite discontinuity Maple outputs "undefined" as in the simple case: int(1/x,x=-1..1);

and with some I get "Infinity", as in the case: int(sec(x)^2,x=0..Pi);

What is the nuance in play here?  Is it with the math or with Maple?

vectors...

I was hoping to give my calculus III students a short introduction to using vectors in Maple.  I wanted a few simple things like plotting vectors in three space.  I loaded VectorCalculus.  Got the dot product and cross product to work, and I can plot one vector -- although it looks more like a telephone pole with a cap than a simple arrow.  But despite all my attempts to give plotvector a list of vectors, I am completely unsuccessful.  There has got to be a better way.  I'm quite frustrated after searching through documentation for several hours.  I'm cert

updating a correlation matrix with a slider...

hi,

how do I write a procedure to update a correlation matrix when I move the slider?

a quick question...

hey guys i need help answering the following questions using maple for my calc II class... any help at all would be great... thanks 1.) Find the area of the region that is bounded above by the curves f(x)=10ln(x) and g(x)=4-(x^4)-x and below by the x-axis. Then for the next two questions use the region that is obtained in question 1. 2.) Find the volume of the solid obtained by revolving this region about the x-axis. 3.) Find the volume of the solid obtained by revolving this region around the line x=4. Thanks guys

Plot involving non-trivial zeroes of zeta function...

My problem statement is here - mathbin.net/5767

Now,  I want to know if this would be relatively simple to plot?  I hope to find a table of the non-trivial zeroes somewhere to save maple computing them.  If I did that, does anyone know how I would plot this?

For anyone interested, this is supposed to simulate the prime counting function.

Thanks,

tom

Palindromes in Maple...

Hey there everybody. I've been working on the Project Euler (projecteuler.net) problems for a while now, using Maple or J to solve the problems. Some of the problems involve using palindromes or testing for palindromes. I know I can convert the number into a string, reverse it with StringTools, and then parse it back into a number, but that requires a lot of time and resources (the PE problems should be solved in under 1 minute).

Inverse of an Integer...

Hi, i have to calculate inverse of an integer modulo p in maple, which i have calculted using a^-1 mod p command, now i want to make a gui for this, i have made a gui using maplet but unable to execute. Anyone plz help me out, how to do this

Syntax for Maple.ini file - Maple 10...

I'm trying to add a path for the Syrup library to a Maple.ini file in a Windows XP system. The existing library path that shows when I execute libname is "F:\\Program Files\\Maple 10/lib" The Syrup library that I want to add is at F:/Program Files/Maple 10/Syrup/maple.lib What is the correct syntax for getting this path into a maple.ini file? phil kenny

Solving for a particular term...

I have the following equations currently in a maple program. I would like to solve for POc in terms of miu, uA1 (or uA2 it doesn't matter since they are equal), L, LTJ, h, b, and PT. I tried the solver, which does not work. I also consider the eliminate function, but I played with it too long and have now given up. Any ideas?

uT1:=uB1*h/H;

uB1:=uTJ1*b/h;

uTJ1:=uA1*h/b;

uA1:=uF1*h/h;

uTJ2:=(PTJ1-PTJ2)*b^2/(3*miu*LTJ);

uA2:=(POc-PTJ1)*h^2/(3*miu*L1);

uB2:=(PTJ2-PT)*h^2/(3*miu*(L-L1-LTJ);

eq1:=uTJ1=uTJ2;

eq2:=uA1=uA2;

remove legend box...

Can anyone please tell me how to remove the box outside of legends? I cannot find where this is documented.

f(x)=g(x) Warning, solutions may have been lost...

I have newbie problem with these two equations:

f(x) = 0.5x-3x-x+x+10
g(x) = xe

I am supposed to draw them in Maple and solve f(x) = g(x), this is what I've got:

f:=x->0.5*x^4-3*x^3-x^2+x+10;

g:=x->x*exp(1)^(0.5*x-1);

plot([f,g],-4..8);

Now I get the drawing and it seems okay, but then I try using solve to do f(x)=g(x)

solve(f(x)=g(x));

plot legend of lines with symbols (solidcircle, so...

Hello, I was trying to plot some graph in Maple.

I wanted to plot few lines decorated with circles, boxes, etc.

Finally I created that figure: http://www.rafalnowak.pl/upload/exampleChebyshev.png

I did by combining plot and point commands into display procedure.

Here is an sample:

intersection...

How can i find of the intersection two great circles on the sphere?

Thanks...

h1:=spacecurve({[x,y,z]},t=0..Pi,scaling=constrained,color=blue,thickness=3):
h6:=rotate(h1,a5, [[0,0,0],[n1,n2,n3]]):

Is possible Integrate this >...

I can't integrate this

Can Maple do it?
