It can be done this way:

use RealDomain in limit(Int(x^(-1/3),x=-1..b),b=0,left) end;
                                 -3/2

may be the issue. I have these settings:

Configuracion regional y de idioma > Opciones regionales> Estandares y formatos: Ingles (Estados Unidos)

Configuracion regional y de idioma > Idiomas > Servicios de texto e idiomas del dispositivo de entrada > Configuracion> Idioma predeterminado del dispositivo de entrada: Ingles (Estados Unidos) - Estados Unidos

Servicios instalados EN Ingles (Estados Unidos) > Teclado > Estados Unidos

and I get 1.50.

Eg:

p := 2*x^2 + 3*x - 5:
coeff(p,x,2);
                                      2

 

of the expression, 'evalc' may work:

evalc(sin(a(r)+I*b(r)));
            sin(a(r)) cosh(b(r)) + cos(a(r)) sinh(b(r)) I


polynomial solution of degree 5 or less:

d:=diff(y(x),x)*diff(y(x),x$3)-diff(y(x),x$2);
yp:=add(a||i*x^i,i=0..5);
eval(d,y(x)=yp):
collect(%,x):
{coeffs(%,x)};
solve(%,{a0,a1,a2,a3,a4,a5});
{a0 = a0, a1 = a1, a2 = 0, a3 = 0, a4 = 0, a5 = 0}

A first integral is y''=ln(C1*y').

can be stated in the maple.ini file.

The way you write bc2 to bc4 implies that the parameters become function calls, like A(0). You should first transform the derivatives to the operator form:

E*MI*(diff(w(x), `$`(x, 3)))/(A*G)+(diff(q(x), x))/(A*G)^2+diff(w(x), x);
convert(%,D);
eval(%,x=0);

is a problem here:

sin(x+Pi/2);
                                cos(x)

So, better leave the phase as 'phi', say:

s:=v(t) = -I0*sqrt(L)*sin(t/(sqrt(L)*sqrt(C)))/sqrt(C)
+V0*cos(t/(sqrt(L)*sqrt(C))), i(t) = -sqrt(C)
*(-I0*sqrt(L)*cos(t/(sqrt(L)*sqrt(C)))/sqrt(C)-
V0*sin(t/(sqrt(L)*sqrt(C))))/sqrt(L);

applyrule(cos(x::algebraic)=sin(x+phi),subs(s,[v(t),i(t)]));

There is some support for pattern matching in Maple, eg:

applyrule(a(u::symbol,v::symbol)=a(f(u),v),sin(a(x,y)));

                           sin(a(f(x), y))

You can get the result, a surface of revolution, this way:

Student[Calculus1][SurfaceOfRevolution](sin(x) , x=0..Pi, output=plot);

Apparently, the reason that Maple uses only the bundled Java is that testing was done against this version. So, it may have more problems with some other

.

 isolate(eq,P^2);
                                                    3
                                           2       a
                                          P  = - ------
                                                 -m - M

Do not claim for the minus signs :)

The property 'continuous' is mentioned in ?property:

A property can be:
(1) a property name, for example, assume(f, continuous)...

but I do not see any example or description of its use. I do not find obvious for me how it is intended to work without an specification of a domain where this property holds. May be that a default is assumed (eg -infinity..infinity)?

It appears that somehow this property should be dealt as in 'iscont':

iscont( tan(x), x=0..1);
                                 true

iscont( tan(x), x=0..2*Pi);
                                false

If you use arrows for vectors, there should be one above B.

It may depend on your input. I will not try to open your worksheet.

One thing that you may try is:

1. Suppress all the output: From the menu, in View >  Show/Hide Contents , unselect Output.

2. Select all the input, Edit > Select All, or Ctrl-A

3. Copy to the clipboard, Edit > Copy or Ctrl-C

4. Open Classic GUI and paste the input: Edit > Paste, Shift-Insert or Ctrl-V

If you have not used "special" symbols, you can use your code right away. Otherwise, you will have to edit.
