There are dozens of indefinite integral expressions in my worksheet. Everytime I execute the entire worksheet, the cursor always rests beside one indefinite integral expreesion and Maple stays in "Evaluating...". Even 30 minutes passed, the result of the integral couldn't come out. What bothers me is that the cursor would rest beside different indefinite integral expressions. For example, I write 4 indefinite integral expressions A, B, C and D one by one. First time, the results of A, B and C come out and the cursor rests beside D with "Evaluating...". Next time, the results of A and B come out and the cursor rests beside C with "Evaluating...".

Before the indefinite integral expressions, I wrote dozens of lines of codes aiming at assigning values to variables. As I typed more and more indefinite integral expressions into the worksheet, even evaluating the codes aiming at assigning values would spend more and more time.

Does Maple evaluate the codes line by line from the top to the end of a worksheet? If it is true, why evaluating the codes before the indefinite integral expressions becomes slowly?

How to evaluate the entire worksheet without stuck in one indefinite integral expression?

Hi everyone, this is my situation:

I've created a program inside a "Code editor region" within "Document mode" which I execute by pressing CTRL+E within the code editor region.

The program outputs an animation of the solution to the heat equation.

The thing is, the program contains some for-loops and I want to print some text in the end of each iteration within the for-loops so as to track the progress, e.g. I want to have printed        "The equations for time level k out of m were set up"

The problem is that in document mode you will get a huge amount of text added to your document which you'll have to delete, if you print about 1000 times.

So my question is:   Is it possible to use the "Command-line Maple 2015"-tool and/or modify the way I've set up my program such that the print statements are outputted to the terminal AND the animation pops up in a seperate window?

I've tried to run some simple commands in the maple-terminal such as:

        plot(x^2,x=-1..1);

but somehow the terminal displays it using regular text-symbols and stuff. I thought that it would just open up some seperate window, displaying a graph-plot as you would normally see in maple.

Hi!

In Mathematica 10.0 were introduced regions with functions like TransformedRegion, ReginIntersection, etc. Moreover, it is easy to check if a point is inside a region, etc.

I would like to ask if in Maple I could use some API with similar functionality?. For instance, I would like to get integer points which lay inside an intersection of two cubes. How I could do this in Maple?

How to get the approximation of definite integral if explicit integral could not be found?

If explicit integral could not be found, is there any function or method to get the approximation of a definite integral?

Hi guys,

I can not convert a series with label.

If anyone can confirm this?

p_tin the file I upload is a complicated expression containing θ and r. Will the accuracy of the result be affected if I use the second method in the file to calculate the definite integral?

I'm trying to plot a piecewise function whose return value has units, but I get an error saying that it found a "name" (i.e., the unit symbol).

Example:

> f := t -> 2*t;

> fp := piecewise(f(tt) <= 4, 1*Unit(W), f(tt) > 4 and f(tt) <= 8, 2*Unit(W), f(tt) > 8, 3*Unit(W));

> plot(fp, tt = 0..10);

I've tried using the option useunits, but no success. Any help will be appreciated.

hi.i encounter error in pdsole equations with unknown parameter(N)??

please help me for solve it....thanks alotmaple_prime.mw

Dear friend! Hope every thing going fine with you. I need the solution of the following inqulity (for what values of a[1], a[2] and a[3] the equity hold) and it simplist form. 

3*a[1]*a[2]*a[3]-2*a[1]*a[2]-2*a[1]*a[3]-2*a[2]*a[3]+2*a[1]+2*a[2]+2*a[3]-1 <= 3*a[2]*a[1]*a[3]-((a[1]*a[2]*a[3]+1)/(a[2]*a[3]-a[3]+1)-1)*((a[1]*a[2]*a[3]+1)/(a[1]*a[3]-a[1]+1)-1)-((a[1]*a[2]*a[3]+1)/(a[2]*a[3]-a[3]+1)-1)*((a[1]*a[2]*a[3]+1)/(a[1]*a[2]-a[2]+1)-1)-((a[1]*a[2]*a[3]+1)/(a[1]*a[3]-a[1]+1)-1)*((a[1]*a[2]*a[3]+1)/(a[1]*a[2]-a[2]+1)-1)

I am waiting your quick response

Mob #: 0086-13001903838

It is given 

   xⁿ (n x - n - x) / (x-1)² + x / (x-1)²  , n is a (symbolic) positive integer.

I want to transform it into

n xⁿ⁺¹ / (x-1) - x (xⁿ-1) / (x-1)². 

How is it possible?

I tried the  simplify, convert (parfrac), collect, combine, expand,  with/without assuming.

Thanks in advance.

Hi everybody,

Ever since i updated to maple 2015, the output of calculations display a disproportionate amount of zeros. For instance:

If i write:

2.3*10^(-4)

i get:

0.000230000000000

Is there anyway to make maple NOT display the last 10 zeros? I've tried Tools ->Options ->Precision -> Round screen display to X. But then it rounds all results to that X amount of digits, wich is also anoying. Like, if i set X to be 10, it'll write 3.000000000 instead of just 3.

Hope someone can help me :-)

I a working with circuits, and was wondering whether or not it might be possible to shorten the proces of calculating parallel resistors. My idea is that using some symbol, such as || would find the equivalent resistor.

My idea is based on the fact that CrossProduct can also be done using &x command. Like so.

CrossProduct(a,b) = a &x b

So for resistors it would look something like:

Parallel(a,b) = a || b

For those interested the function for parallel resistors would be:

Parallel := (a,b) -> 1/(1/a+1/b);
