How do I find the maximum value of k by putting dw/dk = 0? Also, how to find the range of k for which w is real?

So I have a problem when copying multiple output from Maple to Word. I am using a simple example here. 

When I copy each part of the output as an image SEPERATELY, it comes out much cleaner than if I highlight everything together and then copy. Is there a reason this is the case and is there a way to fix this problem?

Here is the Maple Code:

with(plottools);
with(plots);
ttt1 := textplot([0, 1, "3  +  5  =  __", color = "black", font = ["Arial", "bold", 120]]);
display(ttt1, size = [1000, 200], axes = none);
ttt1 := textplot([0, 1, "1  +  3  =  __", color = "black", font = ["Arial", "bold", 120]]);
display(ttt1, size = [1000, 200], axes = none);

I also uploaded the Maple Worksheet

Here is the output:

There are TWO imges in the output in this example. I tried copying both together and pasting them, and then I tried copying them individually. The output is very different in quality.

The one copied alot is much cleaner once copied and pasted in Word. Does anyone why this is happening? I don't want to have to copy images individally for obvoius reasons. I know this example is only two images but what if there was alot more, etc.

Thank you

Hello there, 

Is there any chance to ask if there is a way to simplify the numeric outcome from an operation?

Here is what I've been trying:

I tried to simplify the Eigen values, to make them in the formality of the 'Desired' numerical expression, but no success yet. 

Thank you,

Consider this matrix

a b c

b c a

c a b

I would like to reference the entries with letters, not numbers.  The b,c entry would be a, for instance.  Any way to do this?

If I draw a new molecule in chemdraw and save can we input it in someway and get the 3D coordinates , 2D , and many other details which we can get from the structure.

As I am new and I am planning to buy this toolbox please kind help

Hello,

    I am manually re-creating the TS diagram for phase plot of fluid=air for use in a report as a pretty plot.   The TemperatureEntropyChart function is colored in grayscale.  I really need to change to colorized for additional data being added.

   The code to generate the various isobars color gradient is shadebetween two curves.   

    Using the code method to plot leaves white gaps in the discontinutiy of the plot curves returned from the Property function at the liquid and vapor lines.   I have manually connected the horizontal "under the dome" in a matrix of X,Y for each of two isobar curves.

   However, the shadebetween doesn't seem to like the two X,Y matrices for the curves as inputs to shadebetween.

    So,...   Q:   1.)  Can the color be changed using the TempertureEntropyChart function,..or
                      2.)  Can matrices of unequal X,Y values (scatterplot type data sets) be used for the curves in shadebetween command?  The help infers the Y (v, of (u,v))  values need to match.

Thanks,
Bill

Give a Data for regression in excel sheet with many independent variables as much as 50 and one dependent variable. where first row is dependent variable say

Is their anyway in maplesoft to split into Train and test set 

Then it choose only best set of independent variables to model the dependent variable Y Linear regression

Is their any Toolbox or anyway we can do it

Can anyone help to write a code for this in Maple

Kind help.

Please help with a sample example program Kind help

Hello guys
Could someone help me create a simple palette to contain, for example, three functions that I use constantly?

           conve1(a), conve2(a) and conve3(a).

I tried through the help documentation, but I couldn't.

Sincerely,
Oliveira

hello. i write a for loop and i want to maple give me the answer like the below pic
thanks in advance

for oo to 2 do
    M[oo] := EI*(4*theta(oo) + 2*theta(oo + 1))/L;
end do;

Hello,

I use Maple 2022 on a MacBook Pro. In most of the plots I create I use symbol=solidcircle and symbolsize=12.

Is there a way to make those (and perhaps oher) settings user default so I don't need them in every plot command?

Thanks.

After studying the plottools:-transform command, I intend to visualize the following regions with constrained parameters in : 
 

But Mma gives 

The first instance (with default settings) is the same, but as for the second instance, which graph is correct? 

restart;
with(plottools):
with(plots):
transform((u, v) -> [u^3 - v^2, u^2 - v^3])(inequal(Or(u^2 + 4*v^2 <= 4, And(u^2 + v^2 < 4, (u + 2)^2 + 2*(v - 1)^2 <= 2)), nolines));
transform((s, t) -> [s^2*sqrt(t)*cos(t), s^2*sin(t)])(inequal(`and`(1 <= s, 5*s <= 5 + t, t < 5), s = 1 .. 2, t = 0 .. 5));

I take the liberty to rephrase my previous question as I believe the title was not very clear and so maybe some power users did not look at it. I am making the transition from Mathcad towards Maple and get stuck solving the equation in the attached worksheet. In mathcad I would solve it like this:

How can I achieve results in Maple? I know it is a very powerful program but for me the learning curve is at this moment quite steep. Any help would be very much appreciated.
