How to find the maximum natural number n s. t. the sum of its cubed digits is greater than or equal to n? Of course, with Maple. The same question for the sum of the  digits to k-th power. Here are my unsuccessful attempts:
1.Optimization:-Maximize(n, {n <= convert(map(c ->c^3, convert(n, base, 10)), `+`)}, assume = integer);

Error, invalid input: `convert/base` expects its 1st argument, n, to be of type {integer, list(integer)}, but received n


2. for n while n <= convert(map(c ->c^3, convert(n, base, 10)), `+`) do print(n) end do;

                               2
                               3
                               4
                               5

I am facing a problem in maple 17. When I am launching maple 17, each time  the evaluating process is automatic started in server 1 without any input. I could not interrupt this evaluating process. For removing this problem I reinstall maple 17, but the problem is exist.  Please inform me soon how remove this problem ?

Maple responds with FALSE, but for which real number is the statement false?

restart; assume(x, 'real');

verify(abs(x), sqrt(x^2), {'equal'});

kind regards,

Hello,

I'm very interested by this function so as to export my code Maple as MATHML thanks to the function ExportContent.

However, this function can be applied only to a expression.

I would like to apply to all the code of my worksheet.

Do you have some ides to apply ExportContent or equivalent to obtain the MATHML transformation of a whole worksheet ?

Thanks a lot for your help.

Best regards,

Hello,

I need to prepare for a final exam for a introdutory computer science course in Maple.
My professor gives us mutliple choice questions, short answer questions and wiritng some codes.

what is the most efficient way to study for my final exam? or how should i study for an computer science exam. I am not really use to preparing for such a course. 

Are there any websites that i can practice multiple choice questions?

I would appreciate any advice.

Thank you very much.

Dear friend! Hope you will be fine, I want to general matrix for m by m order. The file attached. I am waiting kind response.

solve 30a+75b+110c+85d+255e+160f+15g+12h+120i=8000 over the positive integers

can I extract a certain non numeric degree from an expression?

for example, I want to get degree "n-1" from "x^(n-1)+y".

any thoughts? 

Hi

I have 2 sets of data and I need to plot them as histograms on the same axis(superimposed). Is it possible to do it using Maple 12? Right now I only know how to plot them in different axis.

Thanks

Here we have a very brief introduction to the use of embedded components, but effective for the study of the polynomials in operations and some products made with maple 2015 to strengthen and raise the mathematics today.

I know this has been asked a lot, but I just want to know if there is a way to ask Maple to only show like maybe the first 1000 results instead of the whole 100000+ results? That way I don't need to overload Maple.

I googled everywhere for this and most results just tell me what diff and D does...

Basically I have a function, let's say

f:= x -> x^2

How do I turn the derivative of f into a function?

I tried

fprime := x -> diff(x^2,x)

But tihs just shows me diff(x^2,x), instead of x -> 2x

Starting with Maple 18, the Print to PDF feature caused the document page to be hard-aligned at the left margin of the page. Maple 2015 still seems to have this problem / bug.

Does anyone else have the same problem? Has a work-around been posted? Is a fix in the works after nearly 9 months?

WHen I type:

I get nothing, a blank box. But if I change the code slightly, by squaring both sides, then it works.

What is the reason for this. I uploaded an image of the output:  http://prntscr.com/752mtd
