sorry my englis is some bad.

 

I want a small text to appear when I hoover the mouse over some specific points

in the pascal triangle (code below) . How can this be done ?

Maybe programming the point probe (instead of getting coordinate in the plot toolbox getting some text for different coordinates)

with(plottools):
with(plots):
rotate(textplot([seq(seq([i-j, j, binomial(i, j)], j = 0 .. i), i = 0 .. 12)], axes = none, font = [times, roman, 16]), -3*Pi*(1/4));
 

After multipication,I got some [  ],like these

(1.388888889*10^(-7)*omega^4+3.429355280*10^50-1.000000000*10^(-36)*omega^6-1.543209877*10^22*omega^2)*bbbb^3+(1.924500898*10^5*omega^2*[-5.702224882*10^14*bbbb]+[4.064421073*10^48*bbbb]+1.666666666*10^5*omega^2*[-3.292181070*10^14*bbbb]-2.000000000*10^(-24)*[-3.292181070*10^14*bbbb]*omega^4)*bbbb^2+(2.777777776*10^16*[-5.702224882*10^14*bbbb]^2-1.000000000*10^(-12)*omega^2*[-5.702224882*10^14*bbbb]^2-1.000000000*10^(-12)*omega^2*[-3.292181070*10^14*bbbb]^2+2.777777776*10^16*[-3.292181070*10^14*bbbb]^2)*bbbb

Two options for DEplot, "velocity" and "color=velocity" are referred to in the Maplesoft conference presentation below, but don't work on my Maple13. Were these options ever implemented? Do they require a call to a special package (no mention of that in the presentation below, dated 2005)? These are very nice options, so if you know anything about them or something similar, I'd appreciate very much your suggestions.

 

I used to be able to select, copy, and paste the output of a Matrix, but now instead of copying the output the action copies something like Matrix(%id = 410996784). I am using Maple13/Classic/1D. Any fix? thanks.

I have had success adding units of distance in Maple using the example in the documentation.  However when I perform an addition on units of information such as gibibytes and mebibytes I receive:

"Error, (in Units:-Standard:-+) cannot represent the given unit in the system `SI`"

This behavior seems to be an ugly little non-orthogonality in the Maple language.  I have posted a test case to my files.  I did try the other systems beyond SI however this did not affect the behavior.

How we write this matrix
 

help me :(

I am needing help on how to make an authentication code for a message I send through Maple.

This signature can't just be my name and must be coded in some way. Any help?

Find the volume of the torus (doughnut) formed by revolving the circle x^2 + y^2 = 25 around the line x=6 using the washer method and the shell method on MAPLE?

I wanted to have solve avoid a particular soluton. I was in for a surprise. Consider:

Perhaps the following behavior is to be expected? would someone explain to me why Maple doesn't automatically apply the simplification needed to ascertain the equality and "erroneously" returns false?

 

(-1/x)*ln(1-x)-x+2=0:

please can you tell me how can I solve this equation.

this is my program to calcul pade approximant at n points complex or real. and i want to excute this program with L =40 or more but it can't.

 

L:=4:
P:=add(p[k]*x^k,k=0..L):
Q:=1+add(q[k]*x^k,k=1..L+1):
f:=(-1/x)*ln(1-x):

a:=seq(coeftayl(f*Q-P,x=I,k),k=0..L):
a1:=seq(coeftayl(f*Q-P,x=-I,k),k=0..L):

s:=fsolve({a, a1});
AP:=evalf(eval(P/Q,s)):
 please can you help to improve this program.

Hi, im relatively new to Maple and only use it occasionally to rearrange equations for further use. I would like to express the following equation in the form (V=...) but seem not able to. V(P,T) the equation should express volume V as function of P and T (pressure and temperature). b, c and d are constants EQN := V+b = (1/(V*(4*V-b)^3)-c*V-d)/(P*sqrt(T)*V^2) How can I do this? thanks for any help/suggestions

I am trying to approximate the solution of vi_vh to vi_vh = 1 / sqrt(vx_vh^2 + (vi_vh+vz_vh)^2) with the expression vi_vh = a * vz_vh^3 + b * vz_vh^2 + c * vz_vh + d + e * vz_vh * vx_vh^2 where b and d are zero The approximation is for the region -2<><>
