Hello those who are in this maple primes.

I downloaded maple2015 for Mac, the newest version of the software, and tried to use it to draw a simple figure with plot3d.

But, in the end, I used gnuplot which I had happened to install though it was my first time of using it.

The problem of using my Maple was that it was too heavy and with my macbook, I found it impossible

to have it work properly. So, I am writing my question now.

I used terminal, but as I think it  might be easy to deal with to use editor not terminal itself

though I use the editor from the terminal, I want to know how I can use maple from the editor and what things I 

can do when I do so. In my image, I want to use it like using TeX from the editor.

As for coloring the code, is the best tool one for Maple V yet? And, how can I do after I wrote the code of Maple?

What can I do with emacs and Maple? Can I use emacs like IDE of TeXshop or TeXworks in LateX?

I am glad to hear from you the general concept or procedures of using it if I use emacs and Maple.

Thanks in advance.

Dear All,

Colud you please tell me how to obtain the answer f(b)-f(a), by manipulating the following expression in maple:

Thank you very much. Best regards, Jand

Hello, I have a similary issue with the following post :

http://www.mapleprimes.com/questions/200835-Algsubs-With-Subscripts-And-Powers

In a constraint equation (in mechanics), I need to make these algebraic substitutions :

--> sqrt(xA1² + yA1²) =rF1 
--> arctan(abs(yA1)/abs(xA1)) = aF1
--> sqrt(xC1^2+yC1^2) = rBTP
--> arctan(abs(yC1)/abs(xC1))=a1

I try to do it with this code :

ListAlgsubs:={sqrt(xA1^2+yA1^2)=rF1,sqrt(xA2^2+yA2^2)=rF2,sqrt(xA3^2+yA3^2)=rF3, sqrt(xA4^2+yA4^2)=rF4,arctan(abs(yA1)/abs(xA1))=aF1,-arctan(abs(yA2)/abs(xA2))=aF2,pi+arctan(abs(yA3)/abs(xA3))=aF3,pi-arctan(abs(yA4)/abs(xA4))=aF4,sqrt(xC1^2+yC1^2)=rBTP,arctan(abs(yC1)/abs(xC1))=a1};
for i from 1 to nops(ListAlgsubs)
do Branch1Cons:=applyrule(op(i,ListAlgsubs),Branch1Cons)
end do:
Branch1Cons:= simplify(Branch1Cons);

I have tried with algsubs or applyrule but it wasn't successfull in both cases.

Do you have an idea how can I do to simplify my expressions ? and namely conduct a good use of applyrule function

I join an extract of my code in order to facilitate the troubleshooting.

Thanks a lot for your help.

Dears, When I run calculation in Maple I found an error in matrices. See the file

Hi, I have 10 equation system and 10 unknown variables. I however, want to reduce the equations to 2 with two unknowns. I'm wondering how this could be done in maple. The variables are Y, q, y^d, y^*, y^x, H,  p^d, w, P and Pv. I intend to solve the equations for Y and w. 

Thanks in advance for your help. The maple file has also been attached.

I am planning on getting Maple 18 Student Editon and I am wondering if the calculus palette is in Maple 18 student edition.

Thanks

Hi, I have a function as following:

50*tan(8*Pi/180)=(a1/(d2-d1))*ln(d2/d1)+(a2/(d3-d2))*ln(d3/d2)+((0.6-a1-a2)/(d4-d3))*ln(d4/d3)

where d1=0.01..0.06, d2>=d1, d3>=d2, d4>=d3, a1>0,a2>0, a1+a2<0.6.

I want to get  all the solutions of d1,d2,d3,d4,a1,a2, which satify the equation and the constrains, is there any way to solve this problem by using maple?

Hello, i got the following problem. I have a function, say u(h,e) whith multiple exponents . As long as Maple does not know that u(h,e) is positiv it won't make the simplification and return u(h,e) as expected. From my view i have two possibilites to solve this problem:

1) Define u(h,e) to be positive. Sounds intuitive, but i didn't manage to find the right definition

2) Give maple the function e.g. u:=e+h^2 and simplify the epression in uneval quotes with assumption positive for e and h.

Whereas I have solution 2, the problem is that i would need excessive amounts of uneval quotes '' at the start of my worksheet, not to run out of them.

I definitly need my epressions in unevaluated forms and would be happy to hear any ideas.

Greetings, Fabian

Hi! I just started to use Maple and I play with some of its functions. I have seen in examples related to RegularChain package an output like  [regular_chain, [[-1, -1], [0, 0]]] and I wonder how I should read it. Thanks for any help and sorry if my question is very basic.

Hi,

i make an attempt to plot the solution to

Here is my code :

> with(plots); with(DEtools);
> ode1 := diff(x(t), t) = v(t); ode2 := diff(v(t), t) = -(.8*9.8)*v(t)/abs(v(t))-cos(t)^2;
> MODEL := {ode1, ode2}; VARS := {v(t), x(t)}; DOMAIN := t = 0 .. 150; RANGE := x = -1 .. 1, v = -5 .. 5; COLORS := [BLACK, BLUE]; IC1 := [x(0) = .5, v(0) = .25]; IC2 := [x(0) = 2.5, v(0) = 3];
> DEplot(MODEL, VARS, DOMAIN, RANGE, [IC1, IC2], stepsize = .1, linecolor = COLORS, scene = [t, x]);
>

and the message cannot evaluate the solution further right of .16015784, maxfun limit exceeded (see ?dsolve,maxfun for details)

Any other attemp has failed.

Have you got somme ideas

Thanks

Phil

for a to z1/T1 do ics[a*T1] := [g0(0, a*T1) = r, g0(1, a*T1) = s] end, this loop runs correctly for T1:=1, but gives the too many levels of recursion error for T1<1. In this loop i am inserting equations g0 in a list ics.

sin(Pi*1.0) returns -4.102067616*10^(-10). How do i make it return exact zero?

It looks like the Online Help has now been updated for Maple 2015.

Here's the What's New in Maple 2015 Overview, which is similar to the product pages currently available here.

But we can now also link to and view the online versions of full help pages of new or enhanced commands or example worksheets. For example, dataplot.

I am modeling a molecule.  I have six line segments.  I know the coordinates of their ends as functions of time.  Naively, I would think it would go like this:

define some functions (composites of trig functions, rational functions, etc)

define points 1,2, ..., 6.   (in terms of the functions)

define line1, line2, ...., line6

define structure = union of 6 lines

animate(structure) as t goes from t_0, ..., t_1

How exactly do i do this?

Hi every body:

I have a problem with below function (f(x)), I will calculate values this function with for loop so that values are closer together. for example I will earn 10 or 20 data for this function so that they differences have to be fixed.my means is that I have 10 data like, 50,65,85,90,100,... no 50,100,170,... . that isn't important for me the data increase with constant value but my final data must be closer together. (the maximum number of my data to be taken is 50). 

function is:

f:=(x)->(310*(z+0.5)^0.2)+70

z=[-0.5,0.5]

with regards...

Mehran.
