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);

New to maple. Trying to solve system of four difference equations for four variables in the form:

Keep getting "warning, solutions may have been lost".

Any suggestions on where I go from here? The solution I know exists is not returned in the list of solutions.

Thanks

Hi, all. I'm not too confident in the results of Tolerances. I am very confident in the results of ScientificErrorAnalysis. Sadly, the Tolerances package has an awesome +- operator, while ScientificErrorAnalysis has the bulky Quantity() function. I'd like to define +- to be Quantity, something akin to this:

`&+-` := (a,b)->Quantity(a,b);

Sadly, 

1+`&+-`(2);

In regards to executing a command to output text in color I have stumbled across a minor bug?

Does anyone know a command for using Newton's method to a solve a nonlinear system, particularly this one:

4y^2+4y+52x=19

169x^2+3y^2+111x-10y=10

?

Also, how about this one:

x+e^-1x+y^3=0

x^2+2xy-y^2+tan(x)=0

?

Thank you

Hi all,

I am now helping with the first year maple session in my university. Recently, some of the student are learning both 1-d and 2-d input.

Now we have something like this:

Is this some sort of bug?

I know it has something to do with the 1-d or 2-d or math input, but in short, that's what happens.

Thanks!

I have maple 13, windows xp.

I am just curious about the existense of some way through which I can navigate with in maple worksheets tabs with kepboard shortcuts.

I would really appreciate the help as it is annoying to use mouse again and again for naviagation

Hi! A question regarding animating a rotation transformation defined by plottools[transform]. I can get the shear, translation and stretch to be animated. But when I use the same commands for rotation, the output doesn't appear. Here are my commands attempting to animate the rotation:

with(plots):

with(plottools):

with(LinearAlgebra):

p:=plottools[rectangle]([0,1],[1,0])

g:=transform((x,y)->convert(Multiply(Matrix([[cos(r), sin(r)...

Just curious, something simple really

In standard Maple,
is plot(x²); then 'right-click-on-graph' -> axes -> create second axis the same as plots[dualaxisplot](x²,x²) ?

If so, why wasn't a secondaxis=true/false option made available in the command line?

Is there a way to color the output text from command line, say using printf? 

printf("I want this output to be green for example");

Any alternate ways to produce colored text from the command line?

I'm writing a maple package, and would like to write one procedure GenerateReport(); which will output multiple plots as well as some text and numbers. How do I do this? Seems like I can use print to output the text and then use the plot command as the last line, however if I try to do multiple plots it only outputs the last one.

I am trying to plot the cdf of a binomial random variable, which has jump discontinuities at each of the integers with positive probability mass. Typically, when plotting a piecewise function, one would prefer not to have Maple connect all the points of discontinuity with a vertical line, and discont=true achieves that. Why doesn't the following command yield the expected results:

with(Statistics):

with(plots):

X:=RandomVariable(Binomial(25,.65)):

when i open maple and type characters it diasapears after awhile and cant type anything

and i cant see many characters in special menus

I need to find factors of the eq, but unable to understand use of mod.

> `mod`(Factor(x^5-1), 2);

                            output redirected...

> `mod`(Factor(x^5-1), 7);

            powers=  4    3      2

Hi colleagues...

I use Maple 12. Can i change the color of Maple inputs from red to other color, How??
