### Difficulty with using Explore and plot with parame...

February 17 2015

Hi,

I'm trying to create interactive plots by using Explore to help demonstrate the effects parameters have on functions. I created one successfully to illustrate shifts and stretches of a polynomial:

transform(A,B,X,H,P,K):=Explore(plot(a*(b*x+h)^(p)+k,x=X),parameters=[a=A, b= B,h=H,p=P,k=K],placement=right)

However when I try to do the same with a solved ODE it returns an error message:

Explore(plot(1/(-p*x+x+1)^(1/(p-1)), x = -5 .. 5), parameters = [p = -20 .. 20], placement = right);

Executing this gives the error message:

Warning, expecting only range variable x in expression 1/((-p*x+x+1)^(1/(p-1))) to be plotted but found name p
INTERFACE_PLOT(AXESLABELS(x, ""),

VIEW(-5. .. 5., DEFAULT, _ATTRIBUTE("source" = "mathdefault"))),

parameters = [p = -20 .. 20], placement = right

I'm not sure why it is having difficulty dealing with "p" when it had no difficulty with the first. Any help would be appreciated!

### Latex to Maple TA online tool is broken...

The following is taken from p 328 of the Maple TA manual.

\documentclass[12pt]{article}
\usepackage{ed}
\begin{document}

\begin{question}{Formula}
% This question uses randomized variables.
\qutext{Find the formula for the inverse of the function
$f(x)=\var{a}x+\var{b}$.}

}
% The above code chooses random integer coefficients a and b between
% 2 and 10.
\end{question}

### invalid input when trying to approximate...

February 02 2015

Hello fellow members. I recently got a new laptop, and installed Maple of course. Everything went smoothly until I attempted to approximate an answer.

I got the error message:

"[5] Error, invalid input: expected evalf[] index to be of type posint but received %ARG1"

Approximation works perfectly on my other computer and old laptop.

Any help?

Hello friends;

I want to solve 3 - second orger equations with  6 unkowns.

When i say just dsolve without boundry conditions it is solving but so complicated.

_C6Ci  it is giving like that which i dont know the meaning of Ci.

But with boundry conditions it is not solving .

Thanks.

### maple 18 does not integrate...

February 01 2015

Hello everybody!

My name is Mathew and I am a new member of this forum, and this is my first post, so please be lenient towards me:) I wanted to ask for help since my adventure with Maple 18 was supposed to start yesterday, unfortunately I encountered a problem I couldn't solve myself so far- my Maple 18 does not integrate. At all. It has no problem with differentiating, adding, subtracting and such, unfortunately any type of integral is unsolvable by Maple. I tried typing the easiest functions, such as e2xdx under the integral, unfortunately it is met with following message:

Error, (in int) wrong number (or type) of arguments: invalid option value passed to indefinite integration: {}.

I understood from several tutorials on the internet that this program should not have any problems with dealing with such form of formulas. What could be wrong? How to make  it work as it is supposed to?

Please help me. As I mentioned in the beginning, I am a new member, so in case I did something wrong or placed this post in wrong category- please forgive me;)

Hi, I installed Maple 17 a while back and was able to work all the commands but recently I reinstalled it
I tried a command which gave me an error that I never got before

>rightsum:=RiemannSum(1/x^2,x=50..75,partition=25,method=right,output=plot);

Error, (in Student:-Calculus1:-RiemannSum) external linking: error loading external library statshw.dll: The application has failed to start because its side-by-side configuration is incorrect. Please see the application event log or use the command-line sxstrace.exe tool for more detail.

When I tried to reinstall the only issue was that it had trouble installing Visual C++ 2005 redistribute however I already have it on my computer and I don't intend to uninstall it since it took a long time to actually get my other programs to have it working. Is there anyhting I can do to fix this error? (Plotting other stuff seems to work fine except for Riemann Sums)

with(Tolerances):

a := &+-(2, .5);

b := &+-(30, 10);

evalf(a*b);

with(ScientificErrorAnalysis):

a1 := Quantity(2, .5);

b1 := Quantity(30, 10);

Dear everyone,

I want to deal with experimental data with error. I find two ways to do the job. But  the results are different .Could you tell me which one is more correct?

Thank you.

Barry.

Aslam-u-Alikum. Hope you will be fine. I have some error in the last command of the attached file. I want this type of answer

StressesMultiplication := Matrix(2, 2, {(1, 1) = 7, (1, 2) = 10, (2, 1) = 15, (2, 2) = 22})

### Why "too many levels of recursion..."??...

December 30 2014
1 2

I am a new user of Maple (Dec 2014).  I am trying to calculate an integral related

to mechanical loss.  Temperature is a variable in the problem (as is time), and if

I use a sinusoidal (sine or cosine) temperature-time relationship, I think all works fine.

A difficulty is that the experiments have two-hour hold times(i.e., 7200 seconds) (followed by 22 hours of sinusoidal temperature variation.)

The experiments run for several weeks or months.

I tried using Heaviside functions to model the hold times.(Constant temperature periods)

Now I am receiving errors such as " Error, (in tools/eval_foo/do) too many levels of recursion..."

Probably the Maple code is crude and/or sloppy. Most of the code is simply the setting of constants in the problem.

I will be grateful for suggestions and comments--the file is attached.  Thank you.  John B

### Error in calculus sheet...

December 29 2014

Hello Maple

I am preparing for an examination in Calculus, but my worksheet in Maple 18 doesn't cooperate.

A lot of my studypartners use Maple 16 and they have no problems.

I meet the following error:

- Error, (in solve) invalid input: hastype expects 2 arguments, but received 1

I'm totally sure, that I'm typing correctly, because I write just the same as my studypartners.
So is it an error, which only is seen in Maple 18 and can I do anything to solve the problem?

Kind regards
Anders Kristensen

PS: I can't figure out how to add a picture

### Length of Output Exceeded Error when using tetrads...

I am using the SumOverRepeatedIndices and get a Length of Output Exceeded error. Sometimes if I close the file and restart the program then I get a result and no error.  However, if I recalculate then I get the error.
