I want to plot points when i_t =1,2,3,..,11,12 instead of a continous line displayed in the worksheet I uploaded. How to modify the function? Thank you for helping:)

Occasionally I have need to import 1D Maple expressions into Mathematica, because I believe mma has superior simplify functionality (sorry Maple). Mathematica has its own syntax which (of course) differs to maple.  eg sin(x) in maple is Sin[x] in mma ; ln(x)=Log[x] ;....... I'm aware of the package MmaTranslator, but I think it only converts mma to maple.

so i need some code pls.

(i have bolded the functions which need to be converted)

eg: i/p:

(1/365)*(365*B21*EP*ln(1+i)*(1+i)^B21*hr*kw*p-365*EP*hr*kw*p*(1+i)^(-1+B21)*i-365*EP*hr*kw*p*(1+i)^(-1+B21)+365*EP*hr*kw*p+SC*i)/(hr*kw*(EP*ln(1+i)*(1+i)^B21*p-FIT*i*p+cos(omega)))

o/p:

(1/365)*(365*B21*EP*Log[1+i]*(1+i)^B21*hr*kw*p-365*EP*hr*kw*p*(1+i)^(-1+B21)*i-365*EP*hr*kw*p*(1+i)^(-1+B21)+365*EP*hr*kw*p+SC*i)/(hr*kw*(EP*Log[1+i]*(1+i)^B21*p-FIT*i*p+Cos[omega]))

Hi everyone

I've come across a RAM-issue.

My program creates a lot of plots using millions of variables-values and it eats up my computers memory since I use the plots to make an animation.

The plots are simple 3d plots created using the surfdata function.

How do I save plots into a single file as the program creates them concurrently such that after the program has terminated I can use the plots to create an animation?

and how do I efficiently delete variables I dont not need anymore?

Dear Friends

            Hope everything going fine with you. I want the numerical solution of nonlinear system of ordinary differential equations using RK method. The system of ODEs and their required results are present in attached file. I am waiting your quick response.

Does [Length of output exceeds limit of 1000000] mean that the function couldn't be solved and I have to modify the mathematical model?
If the results are just too long to be displayed, how can I see the results?

how to make physical quantities graphs from RK45 ode bvp convective boundary layer flow rather than using lines

i use lines command copy one by one yje data from the solution

are they any simplest way to sketch graphs for physical quantities like f'', thetha prime versus 3 parameters?

I try to find the exact (symbolic) value of

(-2*sqrt(7)-4)*EllipticK((1/8)*sqrt(2)*(-3+sqrt(7)))^2+4*EllipticE(-(1/8)*sqrt(2)*(-3+sqrt(7)))*sqrt(7)*EllipticK((1/8)*sqrt(2)*(-3+sqrt(7)))

I tried 'simplify' with different options and 'convert'. It would be pi=3.141... as numerical approximation suggests.

Many thanks.

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.
