Help with Solving ODE and Representing ± Sign...

Asked by: salim-barzani 1050

1 hour ago

I tried solving this ODE, but my result is very different from the expected one. How can I correctly obtain the solution? Also, is there a way to include both the positive and negative signs (±) in the equation so that the final result reflects both possibilities?

Slider Plot and Value Substitution Help...

Asked by: Andiguys 65

10 hours ago

0 3

I need to create a slider plot for A10, A11, and A12 by varying the parameters theta, Pu, and a.
I have a syntax ready — could you suggest modifications to make it work correctly and generate the plot?

Additionally, is it possible to compute the values of A13 and A14 by substituting the obtained A10, A11, and A12 values for each combination of theta, Pu, and a from the slider plot?

How to convert statements with comments in 2D-Math...

Asked by: C_R 3222

Occasionally I want to convert 2D-Math input to 1D-Math input. This is either not fully working with comments or changes the format. Example:

Try converting the input below to Maple 1D-Math (select -> right click -> 2D-Math -> convert to -> 1D-Math)

>

(1)

:

>	statement;

(2)

The Maple Input at the top can be converted by selecting the style C Maple Input from the edit tab but the font changes not to the default font for 1D Math-Input;

>

(3)

The above is in italic and not in bold. However the default for 1D-Math Input is the following

>

statement

(4)

Also pasting code with comments in MaplePrimes (function insert code snippet) removes comments.

Any other ways? Ideally, I would also like to convert a whole document in one go, That is probably asked too much.

where is Maple's help page for Abel second kin...

Asked by: nm 11053

I can't find the help page for Abel second kind, class B.

Maple has help page for Abel second kind, class A and Abel second kind, class C. But not for class B.

Here is an example of Abel second kind class B

ode:=(3*t*y(t)+y(t)^2)+(t^2+t*y(t))*diff(y(t),t)=0;
DEtools:-odeadvisor(ode)

I wanted to know the difference and the transformation used for class B to make it Abel first kind.

I googled and can't find it. Also local help skips over class B.

Is this documented somewhere else?

btw, find error on the help page for class A. Transformation used is wrong. Will leave this for another question.

Maple can do the work with physics of fluids?...

I'm not currently working on the topic of fluids and I'm not very familiar with it. However, my partner is working on it and is using other software. They have a question about whether Maple can handle this kind of work. Are there any examples available? I’d appreciate any help

thanks!

Dear Maple experts,

is there a possibility/command to get a vizualization of the output of the command FeedbackConnect?

I was thinking of something like this:

as it is given on the maple-help page for that command (but not generated via a maple command as far as I understood)

Thanks in advance !
