Dear Maple lovers,

As a classical worksheet user from the past years, now I'd like to be a "modern" Maple user, using the 2D Input in the modern worksheet mode (I will call it mwm from now on). But, alas, I cannot even solve a simple equation!

To describe my situation let me state the following:

1. I use 64 bit Maple 14 Student Edition (single user) under 64 bit Windows 7.

2....

Hello,

I tried to compile the Java program located in $MAPLE/samples/OpenMaple/Java/simple under Linux.

While compiling worked, running the .class file results in a crash of th jvm:

# A fatal error has been detected by the Java Runtime Environment:
#

    My first touch with Maple was in 1997,when I was in my undergraduate course.The software of maple was in three floppy disk.

    Since 2000,I becomes a teacher for mathematics .Now I am using it to compute the integrate,limits,etc.

Hi,

When I solve this equation

Y(lambda):=_C1*sin(lambda*L);

solve(Y(lambda)=0,lambda);

Where _C1 and L are constants, I get 0.

But the solution of this equation which is easy is lambda=n*Pi/L where n=1,2,3,...

Why?

Thanks

This is what I'm trying to do:

> d := 40*Unit(m);                      

> a := .170*Unit(m/s^2);

> x := d+(1/2)*a*t^2;

> plot(x, t);

Error, (in plot) the units `m` and `m/s^2` have incompatible dimensions

Is there any way to tell Maple that my t is a variable of seconds?

This post is a further development of my earlier question in reply to John's post. I have implemented a basic version of the CANDECOMP/PARAFAC algorithm referred to on Wikipedia and described 

i'm trying to run the following procedure:

> restart; with(LinearAlgebra);
> test:=proc(alpha, beta);
print(`output redirected...`); # input placeholder
Error, unterminated procedure
         testAssignTypesetting:-mambiguous(

           procApplyFunction(αcomma β),

           Typesetting:-merror...

This is not really the next part in my randomness series, but more of an aside.  I used Maple's embedded components to use the Lotto649 drawing data from my last post to create a historical lottery simulator.  Basically, you fill in your prefered numbers, and it simulates you playing the lottery in every draw since 1982.

>f:=x->(1/sqrt(1+x^3));  I typed this function into Maple, but I keep getting: Error, missing operator or ';'. I'm not sure what I'm missing!

Dear primers,

i read in a list of data (which are called roi), then i would like to fit these data (done in this case by a spline function) and compute the values for y=0.3.
for some reason, maple (i am using maple14) gives me only one value instead of two.

i would be happy if somebody could give me a hint how i get both values.

Hello,

I was following the Getting Started tutorial wher it shows how to do a Taylor series expansion about z=2, for a 4th degree poly.  Maple returns

error, unable to parse 'mverbatim'

Further in the tutorial it asks me to type (x+2y)^3 when upon pressing enter, it returns the same error.

What can be done to correct this error?

Thanks,

Cary M.

the problem is as follows:

if((a>0) and (b>0) then (c:=2*a, d:=3b, e:=9b.....)

elif ((a<0) and (b>0)) then (c:=.., d:=..., e:=....)

elif.....

.....

else c:=..., d:=..., e:=...

end if

i know i have the if conditions right, but not sure about sequential conditions..what is the correct syntax for this??

I'm getting errors like parse errors, unterminated if, and invalid sequence (on the :=)...

The well known(!) Heun's equation is,

df:=diff(y(z),z,z)+(gamma/z+delta/(z-1)+epsilon/(z))*diff(y(z),z)+(alpha*beta*z-q)/(z*(z-1)*(z-a))*y(z) = 0;

The solution is the general Heun's functions and it should be written as HeunG according to the help file of Maple 14 but my solution is found in terms of some function called HG which is not listed in the help system.

1. Are they the same?

Hey everyone.

I have a wierd problem when using the "Units[Standard]" addon.

I'm trying to do some simple thermodynamics calculations, and need to raise certain values in an irrational power.

It looks like this:

restart:
with(Units[Standard]):

n:=1.38:
p1:=1.1[bar]:
v1:=3[dm^3]:
v2:=0.4[dm^3]:

p2:=(p1*v1^n)/(v2^n):

If I execute it, I get this error:
Error, (in Units:-Standard:-^) a unit can only be raised to a rational power
