We have new problems, running  in maple 12.02, the example of the website
intpak, function
&cmult_opt displays the following message:
"Error, unable to parse."

This problem does not occur if the function is executed in a worksheet with
extension mws.

The other problem is with the function compute_all_zeros_with_plot:

"Error, (in plots:-display) cannot make plot structure from object with name
textplot"

What is the best way to create the equivalent of Matlab stem plots in Maple? (i.e. discrete point plots with a vertical line down to the X-axis - usually used to illustrate a discrete sequence)

 

 

Which can be solved simultaneously to give estimates for a and b by Maple

{Psi(1,b)-Psi(1,a+b)} / {Psi(0,b)-Psi(0,a+b)}= s₂/s₁

{Psi(2,b)-Psi(2,a+b)} / {Psi(0,b) - Psi(0,a+b)} = s₃/s₁

All:

I am trying to export a shaded plot with the transparency set to approximately 0.5 so that the gridlines are visible under the shading.  I am exporting it as an EPS for viewing in Ghostscript and/or LaTex.  Here is a simple example.

pf:=plot(x,x=1..5, view=[0..5.5,0..5.5], gridlines=true, tickmarks=[5,5], thickness=2);

pfshading:=plot(x,x=1..5, view=[0..5.5,0..5.5], gridlines=true, tickmarks=[5,5], filled=true, color=COLOR(RGB,.7,.9,.7), transparency=.5);

display(pf,pfshading);

I am very inexperienced with Maple. I have v.12. I was wondering if there was a way to represent diff(int(abs(x), x = cos(t) .. sin(t)), t) in an animation, showing the area under the abs function with the bounds changing in a loop.

Hi,

I am totally new to Maple and need to solve 2 non linear (algebraic) equations with 2 unknowns simultaneously. Can someone please help and tell me how to do this???

Thanks

i have rotated a point on the sphere with rotate command. i found the new points coordinates but I can not use them. How can I use the new coordinates?
thanks..

 

I'm pretty new to Maple. I've been using MATLAB for quite a while but it isn't very convenient for this problem. My first question is if it's possible for Maple to do partial derivatives for a function with two variables. Here's an example of what I am doing.

W = Q*qA - P(qA - (qA-qE)/2) - (1/2)*k1*(qA - (qA-qE)/3)^2 - (1/2)*k2*(qA - 2(qA-qE)/3)^2;

(Maple cleans that up quite nicely)

Now I want to take the partial of W with respect to qA as well as the partial of W with respect to qE. So I should get something like this:

dW = Q*dqA - P(dqA - dqE)/2 - ...

Hay dere. I've come across a nonlinear equation system which i've tried solving in maple through matrices. Maple's own solve function for systems didn't work out (just threw back gibberish at me which i wasn't able to simplify (root of Z etc)) and i really don't know how to approach the problem. Any suggestion on how to solve it would be appreciated.

The problem is as follows:

0 = 22 - 44t + 216t - 66u - 450u + 362u
0 = 150 - 300t + 185t - 450u + 795u - 495u

  Hello,

 

Hello, this is kind of a newb problem, and isn't even terribly important cause it's just an irritant, but I'd love to know how to get around it. The problem s that Maple occasionally pulls constants out of fractional equations and puts them separately at the front. This might sound confusing so here's an example of what I mean. Take the following two equations: sigma[1] := (sqrt(T^2+1))/(4*(K+sqrt(T^2+1))); sigma[2] := (sqrt(T^2+1))/(4*K*(1+sqrt(T^2+1)));

I'm trying to plot the following simple procedure with conditional check.

> t := proc (x) if 1 < x then x else x+1 end if end proc;
print(`output redirected...`); # input placeholder
proc(x) ... end;
> plot(f(x), x = -1 .. 4);
%;
Error, (in t) cannot determine if this expression is true or false: 1 < x

I get this error. Any thoughts?

 

Hello,

Is there any way to plot complex numbers in polar form in maple 11? I have looked around the help section as well as these forums (where I found one post on the subject), but I have still not gotten any closer to it.

Any help would be greatly appreciated!

Thanks

I use Maple 11 on windows (Processor Intel Centrino 1.4 Ghz and 512 Mb RAM).

I have problem with plotting of my function. Time of ploting is about 30-40 seconds. I try to use evalhf in different way for my function, but get different errors. My problem is that function in example is the most simple case in my physics model. It is ideal case, but in other not ideal case time of plotting increasing to 200 or 300 seconds. It's very dramatically for me :(

My example is:
