    In thus manuscript i got some reviewer comment which is asked to simplify this expresion and there is a lot of them maybe if i do by hand i  made a mistake becuase a lot of variable so how i can fix this issue and make thus square root are very simple as they demand

    I am trying to factor out I = sqrt(-1) from square roots in my Maple expression by using a substitution f2. However, after applying these substitutions to my final expression, there is no visible change. In addition, the term sqrt(2)/2 + sqrt(2)*I/2 also appear. How can I=sqrt(-1) can be properly factored out from the square roots?

    ...flies around in the spatial Cartesian coordinate system and impacts the coordinate planes xy, xz, and yz with exactly one impact. This creates circular impressions on the coordinate planes in this order, with the radii r1, r2, and r3, which are assumed to be known. From these, the sphere's radius r and the coordinates of its center can be determined?

    Is there a short-cut for jumping to a specific output label in a Maple worksheet?

    I have a Maple worksheet with over 200 labels:  (1), (2), ....., (236) etc?

    export 2D plots with transparent background?...

    Asked by: nmacsai 260
    image export plotting
    August 06 2025

    My goal is to export images of curves where the output image has no background or equivalently, a fully transparent background. Is there a standard way to perform this task? I know that I can do this with the help of external software but I want to do it at the export stage in maple and avoid increasing the number of tools needed to perform the job. Eventually, I may want to generate many thousdands of curves/images with transparent backgrounds. 

    Below I show how to make a plot while choosing a background with the color blue. I have found no way to select a fully transparent background. I expect this background transparency will be applied at the export image stage. 

    how_do_I_plot_with_no_background.mw

    To give an explicit example of what a plot with no background looks like, I make a plot in an unrelated software of a curve with no background. It's impossible to differentiate a white background from a transparent background in this environment, so we also show the same image embedded in an unrelated colored background also generated in an unrelated software.

    In the image below, we can see how a image of a curve with a transparent background can be embedded over top of any other image without the blue square shown the the first example.

    Problem in constructing the monomials...

    Asked by: Muhammad Usman 240
    monomial set
    August 06 2025

    Hi

    I hope everyone is fine and doing well. I want to constrcut the set of monomials {p[0],p[1],...,p[m-1]} for any value of m for example, for m=6 the monoial is define as:

    p[0]:=1;

    p[1]:=x;

    p[2]:=y;

    p[3]:=x^2;

    p[4]:=x*y;

    p[5]:=y^2;

    and similarly for m=10 the monomials should be given as:

    p[0]:=1;

    p[1]:=x;

    p[2]:=y;

    p[3]:=x^2;

    p[4]:=x*y;

    p[5]:=y^2;

    p[6]:=x^3;

    p[7]:=x^2*y;

    p[8]:=x*y^2;

    p[9]:=y^3;

    I am waiting for your positive response. Please take care and thanks
