Is there anyway to prevent Maple from converting a log10 function to a ln function when it displays a result?

hey guys , my concern is about boundaries in random matrix or rtable. so, i can garantee that boundaries in  matrices are in 0 and 10, but i can´t impose a restriction  like the sum of row must be equal 10 for example.
help !!

pop:=(10-0)*ArrayTools:-RandomArray(proc(A)
local i
if A::rtable[row] then
seq(A(i),i=1..NumElems(A));
else
args
end if
end proc(10,3))+0;

Can someone tell me how Maple coding written in worksheet mode can be fully transferred into a Word document taking all maple's commands, alignments and any section's arrows as they apper in worksheet mode?

I found that after using "Export as" (tried everthing there), my worksheet appers to be abrupt, alignment of certain codings changed and all the arrows of sections removed.

Please tell me how to deal with this issue, I need to transfer my maple coding...

Does anyone know what the beneath error stated after the following coding means, can't findthe solution,     Although looked in mapleprimes site, and thanks for Joe Riel who pointed out the same problem in 2010,2 June...
But, it seems there is still no vivid solution for such problem, how to followk:=20:m:=4:
p[0] := 1:
tr := 4:
frame:=100:omega[n]:=sqrt(k/m):
T[n]:=(2 pi/omega[n]):

Can't find what the matter in recursive occurance of this problem. Anyone knows how to sort it out, thanks

p[0] := 1:
tr := 4:

T[n]:=(2 pi/omega[n]):> maxpoint := proc (x) local tr, p1;tr := evalf(x*T[n]):p1 := piecewise(t1 <= tr, p[0]*t1/tr, p[0]):maximize(int(p1*sin(omega[n]*(t-t1))/(m*omega[n]), t1 = 0 .. t), t = 0 .. dur) :

Can someone help me to generate the same, identical grpah over several periods in x-axis? In exact term, I mean that I need to plot a periodical grpah, that repeats itself over the interval? It is like given a periodical function and now have to draw it many times...(function can be any form, not only sine and cosine)

HI,

I want to create a Textbox which will be opened in the beginning of a Maple code. In this Textbox I want to write an integer, which will be used for a following calculation.

> restart; with(Maplets[Elements]);
print(output redirected...); # input placeholder
> maplet := Maplet([["Insert Text", BoxCell(TextBox['IB1'](1 .. 10))], [Button("OK", Shutdown(['IB1'])), Button("Cancel", Shutdown())]]);

for example, how to define f(x,y)=sin(x+y) inside a triangle but f(x,y)=0 elsewhere?

### Grouping the values

A simple question. I have this:

k*(2x+y-3z+2)+s*(5x+5y-4z+3)=0

And I want to group it by x, y, z, so that I would get:

x*(2k+5s)+y(k+5s)...=0

I'm using Maple 11.

I put Celsius in my equation and I get the wrong answer even though I've loaded the Units Package:

I have to put in the conversion to Kelvin by myself to get the right answer:

What am I doing wrong?

Good Morning.

I have a problem

i have two functions

> xcir(t):=0.3 + 0.15*sin(t):> ycir(t):= -0.3-0.15*cos(t):

and i suppose that i have a problem in the following equation
> qd2 := ((arctan(-ycir(t)/xcir(t))-arctan(.45*sin(qd3(t))/(.45+.45*cos(qd3(t)))))*180)/(3.1416);> qd3 := 180*arccos((xcir(t)*xcir(t)+ycir(t)*ycir(t)-.45*(2*.45))/(.45*(2*.45)))/(3.1416);

I am currently attempting to write my own program in maple for the 2nd order Runge-Kutta method for a second order differential equation. What I am finding dfficlut is assigning the initial conditions.  I want to include the condition that

(d(theta)/dt)[0]=v_0 and then proceed to evaluate using different values of v_0, however I'm not allowed to assign a value to a differential.

How do I go about including this condition?

### why does evalc give csgn?

Hi,

I am trying to simplify the expression s as given below. (I am not sure why it comes up with all the vector caclulus notation in it but it should display okay when you enter it)

Because of the presence of the exponential imaginary fucntions I thought evalc might be useful but when I use it I get a huge expression with csgn appearing in it. To my knowledge csgn appears when assumptions are not correctly specified - is this so? I can't see any assumption...
