I put this command and It keep saying  plot(f(x), x = -0.667 .. 1.71, y = -5 .. 20, gridlines); Error, (in plot) unexpected options: [1.71 = -.667 .. 1.71, y = -5 .. 20] . How can I fix this

How can I show all the parameters in title ?

# countourplot3d piggybacks on top of plot3d.
# For the "coloring=[lowColor, highColor]", the "filledregions=true" option must be present.
# If "filledregions=true" is not present, plot3d will throw an error.
# This code shows the three cases, only one of which will work.
Note to support. I cannot add a new tag. contourplot3d should be a tag.

Hi all,

I am quite a rookie in using Maple.

A project is going on while I need to use previous formulas and variables defined in A.mw, while I don't want to redefine everything again in my worksheet, is there any approach to inherit everything in A.mw to my current worksheet?

How would I go about creating a tetrad of a specific signature in the Differential Geometry package. The GrahmSchmidt and NullTetrad give me orthonormal and complex null tetrads. But I was wondering if there was a way to generate a tetrad of specific signature.

The union is simple

with(plottools):
with(plots):
display([torus([1,1,1], 1, 2),torus([1,6,1], 1, 2)], scaling=constrained, lightmodel=light1, shading=zgrayscale,color=[red,red]);

but how to plot the intersection?

I have been try to code the 

mdl:-Fit(x, y, opts)
command in Deep learning package

But i feel new to that command I am making errors 

Can I get a small toy code how to call it and its output on train and test

so that i could learn

kind help please

Hello,
 i want to increase my value monotonically  . but i don't want to do it like sequence. how can i write code.

for example my value ..starts at 0...to some values i just want to increase.
help me plz

CREATING GRAPH EQUATION OF "DNA" IN CARTESIAN SPACE USING PARAMETRIC SURFACE EQUATION RUN ON MAPLE SOFTWARE

ENJOY...

I'm having a symmetric bivariate polynomial P(x,y) with a high degree (larger than 8). I want to know if there exists a root of P(x,y) or not. I may not need a specific root but rather to know if P(x,y) has a root or not. I've been doing some research but I only find the command that helps solve univariate functions or solve systems of bivariate functions. 

In conclusion, my question is: How can I know that a symmetric bivariate polynomial has a root or not using Maple?

Here is the polynomial I want to check

P(x,y)=x^12*y^3 + 10*x^11*y^4 + 43*x^10*y^5 + 105*x^9*y^6 + 161*x^8*y^7 + 161*x^7*y^8 + 105*x^6*y^9 + 43*x^5*y^10 + 10*x^4*y^11 + x^3*y^12 - x^12*y^2 - 8*x^11*y^3 - 17*x^10*y^4 + 8*x^9*y^5 + 82*x^8*y^6 + 128*x^7*y^7 + 82*x^6*y^8 + 8*x^5*y^9 - 17*x^4*y^10 - 8*x^3*y^11 - x^2*y^12 - x^12*y - 4*x^11*y^2 - 62*x^10*y^3 - 341*x^9*y^4 - 902*x^8*y^5 - 1410*x^7*y^6 - 1410*x^6*y^7 - 902*x^5*y^8 - 341*x^4*y^9 - 62*x^3*y^10 - 4*x^2*y^11 - x*y^12 + x^12 - 8*x^11*y - 62*x^10*y^2 - 680*x^9*y^3 - 3169*x^8*y^4 - 7312*x^7*y^5 - 9540*x^6*y^6 - 7312*x^5*y^7 - 3169*x^4*y^8 - 680*x^3*y^9 - 62*x^2*y^10 - 8*x*y^11 + y^12 + 10*x^11 - 17*x^10*y - 341*x^9*y^2 - 3169*x^8*y^3 - 11838*x^7*y^4 - 21793*x^6*y^5 - 21793*x^5*y^6 - 11838*x^4*y^7 - 3169*x^3*y^8 - 341*x^2*y^9 - 17*x*y^10 + 10*y^11 + 43*x^10 + 8*x^9*y - 902*x^8*y^2 - 7312*x^7*y^3 - 21793*x^6*y^4 - 30696*x^5*y^5 - 21793*x^4*y^6 - 7312*x^3*y^7 - 902*x^2*y^8 + 8*x*y^9 + 43*y^10 + 105*x^9 + 82*x^8*y - 1410*x^7*y^2 - 9540*x^6*y^3 - 21793*x^5*y^4 - 21793*x^4*y^5 - 9540*x^3*y^6 - 1410*x^2*y^7 + 82*x*y^8 + 105*y^9 + 161*x^8 + 128*x^7*y - 1410*x^6*y^2 - 7312*x^5*y^3 - 11838*x^4*y^4 - 7312*x^3*y^5 - 1410*x^2*y^6 + 128*x*y^7 + 161*y^8 + 161*x^7 + 82*x^6*y - 902*x^5*y^2 - 3169*x^4*y^3 - 3169*x^3*y^4 - 902*x^2*y^5 + 82*x*y^6 + 161*y^7 + 105*x^6 + 8*x^5*y - 341*x^4*y^2 - 680*x^3*y^3 - 341*x^2*y^4 + 8*x*y^5 + 105*y^6 + 43*x^5 - 17*x^4*y - 62*x^3*y^2 - 62*x^2*y^3 - 17*x*y^4 + 43*y^5 + 10*x^4 - 8*x^3*y - 4*x^2*y^2 - 8*x*y^3 + 10*y^4 + x^3 - x^2*y - x*y^2 + y^3

`debugger/no_output`;

From the Maple 2023 user manual for AudioTools, when I attempt to input:

with(AudioTools):
Tone := f -> Play(Create(x -> evalhf(sin(1/22050*x*Pi*f)), duration = 1)):
Tone(440);

I get the following error message:

Error, (in DocumentTools:-GetProperty) Attempted to retrieve property of unknown component Speaker0.

Clicking the error message in Maple then goes to this page:

https://www.maplesoft.com/support/help/errors/view.aspx?path=Error,%20(in%20DocumentTools:-GetProperty)%20Attempted%20to%20retrieve%20property%20of%20unknown%20component%20Speaker0.

How do I get a function to play as an audio file in Maple 2023?

Is there a way to enclose in parentheses or brackets a highlighted selection of Maple Input?  This is a nice feature on WXMaxima to quickly and accurately enclose any selection of input syntax in parentheses or brackets.  Otherwise it can become tricky to add the opening and closing parentheses/brackets separately.

How do I insert an Input Prompt (">")?

On Maple 2023, each new input is marked on the right-hand side as (1), (2), (3), etc.  This is equivalent on WXMaxima as %i1, %i2, %i3, etc.  On WXMaxima, I can left-click between any two previous inputs to insert a new input, for example %i4 might be between %i1 and %i2 if I added %i4 after %i3.  However, I can't seem to do this on Maple.  Is there a way to go back and add a new input between two previous inputs on Maple 2023?

Likewise, I can't seem to add a new input prompt after the last input prompt if the last input prompt has not executed.
