I want to write two different numbered lists in the same document like:

  1. Item one list one
  2. Item two list one

And the second list:

  1. Item one list two
  2. Item two list two

The problem is that whenever I use the "Set the paragraph to be a numered list item" button, the item becomes a part of the same list as every other list item in the document. How can i separate two lists?

Hello!

how to get a table with Relative Error and Absolute Error in Maple?

I tried in (https://www.maplesoft.com/support/help/Maple/view.aspx?path=Student/NumericalAnalysis/RelativeError) but was unsuccessful.

Thank you!

Hi, how to write a loop and solve the algebraic expression? is the loop and do loop are the same thing? if different then pls mention how to solve the same question by using do loop?

Hello,

When I typ:

> phi; kappa;

It gives symbols φ and K.

I do not want this, I want the words phi and kappa.

How do I turn this off?

 

I understand it has something to do with SYMBOL or a Palette?
I see a Palette left named 'Greek' or 'Trigonometric & Hyperbolic' that have phi in them, but how do I delete a Palette (If that is how I stop these symbols)?


I'm not really good with the software, I just use it for some school work.

Thank you in advance for your help!

Hey

 

Is it possible to draw a slope field for a second order differential equation with initial conditions?

 

Hi

I am asking for your help, as I would like to know if it's possible to integrate a function using SI-units.

This is what I get when I try:

Copied directly:

with(Units[Standard]);
∫10 ⟦m⟧/(⟦s⟧^(2))ⅆ⟦s⟧
Error, invalid differential
                       /      (m)                         
Typesetting:-mambiguous|int10 ----Typesetting:-mambiguous(
                       |         2                        
                       \      (s)                         

                                                                \
  DifferentialD(s), Typesetting:-merror("invalid differential"))|

Why 3D .eps figures produced by Maple 2020 are often excessively large?

So, it´s a little heavy to the viewer and to compile to PDF.

  • How could we reduce the size without losing any quality? 

Is the following function w 

equal to next functions for a=1 or a= -1?

if a=1 then 

w=

if a=-1 then 

w=

where n>1, B,c and k are arbitrary constants.

Hi I have a transfer function first or second order and I want to get it into standard form

Which the transfer function is

of H(s)/(W__I(s) so how height of a tank (H) is affected by incoming flow rate (W__i(s)) but I need to get this transfer function into standard 1st order form

Where I need to find what K and tau are to get it in to this form and tau is always in the units of time. How can I do this in maple? It's pretty impossible by hand I find. I've attached my workbook for it.

Hi,

I am doing some analyses of autonomous DEs (single equation and systems). Maple is able to easily produce 2d- and 3d-phase protraits for systems. However, I am struggling to produce 1d-phase portrait for autonomous first-order DEs. I would like to produce a single axis with some labels and decorations which include the following:

  1. All equilibrium/critical solutions of the DE.
  2. Arrows on the axis indicating if the non-equilibrium solutions are increasing or decreasing in a certain interval.

For example, for dy/dx = -y^2*(5*y-1)^2, would like to produce the plot in the attached file. 

How might I achieve this?
