you have eight non-linear equations in ten unknowns. The unknowns in the system can be indentified using

`union`(indets~([seq(q[j], j=0..7)])[]);

which produces {k, re, a1[0], a1[1], a1[2], a1[3], a1[4], a1[5], a1[6], a1[7]}. Since I suspect that only a numerical solution will be possible (and there may be mutiple numerical solutions), I think the first step is to provide eight equations in eight unknowns!

Hmmmm...

Three points

  1. I agree with Carl that if you want to get the number whihc is the ration of circumference to diameter, then in Maple you need 'Pi', not 'pi'
  2. Your worksheet doesn't actually use units! You have just inserted simple variable names such as 'V', 'W' etc. You can tell because, in the Maple output, these names are 'italicised': if you had entered these quantities as units, then the relvant quantities would not be 'italicised' in Maple output. You can enter units either by using the 'units' palette on the left-hand-side of the interface, or by simply typing *Unit(V)' where appropriate. I prefer the latter, at least partly because not all units are available from the palette. For example, the only palette unit I can find for frequency is 1/s, which is correct - but sometimes one would rather have Hz. I have fixed all of this in the attached
  3. If you load one of the Units() packages - say Units[Standard], then the conversion from V2/W to ohms (ie capital Omega) will take place automatically - see the attached

NB The display of the double square brackets [[..]] around unit quantities is a "quirk" of this website. These brackets do not display in the actual worksheet - honest!

for such a function g(x)!

A simple limit check shows that your integrand f(x)=x/(tan(x)-sin(x)) is infinte at x=0. Hence there is no function g(x) such that g(x)>=f(x), x=0..1, for which g(x) would be convergent

Well, actually, they are the same...

Notice that the integration tutor (for whatever reason) return an inert limit - the word 'lim' in the output is "greyed" out. If one makes this limit active using the value() command then you will get the result you expect

See the attached.

The equation you are trying to solve has a 7th-order polynomial, and so *ought* to have seven roots - which is exactly what Maple returns - see the attached.

Three of these roots are reall and four are imaginary: the non-zero roots all come in pairs, ie have a multiplicity of 2.

I can't diagnose why you are getting anything different, because debugging a picture of code is way more difficult than debugging actual code.. I am however very suspicious of the fact that your answer contains the variable 'msel', when this has previously been assigned to a numeric value????

In future, please use the big green up-arrow in the Mapleprimes toolbar to upload worksheets with problems.

you cannot assign anything to a formal parameter of a procedure within the procedure. Any attempt to do so will result in an error message. The error message varies depending on the type of the parameter.

Consider the attached "toy" example, where the formal parameter is 'x', and the procedure "attempts" to assign a value to it

> 

 aTest:=proc(x)
             local a;
             a:=2:
             x:=a:
        end proc;
 aTest(3);
 aTest(<0,1>);

proc (x) local a; a := 2; x := a end proc

  

Error, (in aTest) illegal use of a formal parameter

  

Error, (in aTest) invalid left hand side in assignment

  1. Can't really see an issue with using the Degrees() package, a couple of trivial example are show in the attached
  2. Since you also mention 'RPM', you may want to consider using the Units[Standard] package, with the default unit for rotational speed set to 'rpm Again a trival example is shown in the attached.

If you continue to have problems please upload the offending worksheet to this site using the big green up-arrow in the Mapleprimes toolbar. (NB units display differently on this site than in an actual worksheet)

In your first case...

you have a 1-Dimensional Array whose entries are lists. This will be converted to a 1-Dimensional Matrix, whose entries are lists.

If you convert the 1Dimensional Array to a list first, then you will get a listlist structure, from which the Matrix constructor will produce a 2-Dimensional Matrix of simple numbers

 

As you have defined...

it, the initial condition D(phi)(0) = phid0, is dependent on the independent variable 't'. That is not an initial condition.

If I take a "guess" at what you intended, then I get the attached, which executes without errors.

According to wikipedia...

here https://en.wikipedia.org/wiki/Fractional_part, there is no agreed definition of the fractional part of a negative number. Three such definitions are in use. Depending on which of these you prefer, the fractional part of -9.8 would be either 0.2, 0.8 or -0.8.

One can get the behaviour you desire by writing a trivial function. See the attached
