I am solving a very simple first-order IVP whose solution can be expressed as v(t) = (10/(3*t+1250))^(1/3). I've tried multiple simplify( ) and combine( ) but I cannot get Maple to simplify the solution to this form. Some of my attempts are in the attached worksheet.

Any thoughts on how to accomplish this?

I am trying to reproduce this visualization of RGB:

Does any one have anything like this for Maple?

I am using GraphTheory:-AutomorphismGroup() command in order to obtain all the automorphisms of a graph. However, the command appears to return a set of generators. How can I get all the automorphisms listed?

Here is an example of my work.

I am trying to produce a two-dimensionanl grid spanned by 2 non-standard vectors as shown below.  How might I achieve this?

I have the set {1, 2, 3, 4, 6, 8, 12, 17, 19, 20} and i need to select all the elements between 5 and 15 and create another set with just those elements. So, I want to obtain the set {6,8,12}. How might that be done using the select( ) command? Other suggestions welcome.
