What is the pattern in the following polynom: (how to generate them)
1: 12 n^2 + 12 n + 1
2: 300 n^3 + 450 n^2 + 160 n + 5
3: 840 n^4+1680 n^3+1030 n^2+190 n+3
4: 1260 n^5+3150 n^4+2730 n^3+945 n^2+107 n+1
5: 27720 n^6+83160 n^5+93030 n^4+47460 n^3+10689 n^2+819 n+5
I have an expression like; 0.7x + 5e-10y, which I would like to approximate to 0.7x.
Round won't work as it will also round the 0.7 down to zero. I have tried using he Digits command, but it seems to only work half of the time.
Is there a simple command that can put a ceiling on a number like e-5, so that any number lower than that will not be returned?
This is probably a simple command, but I cannot figure it out. I am using the following to spit out some results from a system of ODEs, but I can't figure out how to label the individual columns t, H, W R, etc. Any suggestions?
> file := "/Desktop/Aquifer results2/comp60.txt"; try fd := fopen(file, 'WRITE', 'TEXT'); for tt from 0 to 945 do fprintf(fd, "%a %a %a %a %a %a\n", (eval([t, H(t), Weq, Req, price, total], sol2a(tt)))) end do finally close(file) end try;
Curious as to why the whole line, during an animatecurve plot, "wiggles" as it's being animated.
A simple example
Why is that?
I want to make an overloaded function with two possible behaviours.
If the function is called with a list as parameter it shoud make something; if it's called with TWO lists as parameters, it shoud make another thing.
I tried first something like:
I was just wondering about a smart way to diff a vectorfunction. Lets say i want to diff this vector:
When i try to diff v it says:
"Error, non-algebraic expressions cannot be differentiated"
I know it's possible do do by:
But is there a better way?

my Maple sheet is structured in sections. So far, I could not find (Maple Help, Google, Mapleprimes) an easy way of commenting out (i. e. disabling or deacitvating) a section or subsection. Any hints how to do that? (Similar to C++ with its /* ... */ or many (LaTeX) editors with the "Insert comment" function.) Writing a # manually in front of each command is not regarded as "easy".
1: 6n + 5
2: 150 n^2 + 200 n + 55
3: 420 n^33 + 770 n^2 + 410 n + 57
4: 630 n^4+1470 n^3+1155 n^2+343 n+29
5: 13860 n^5 + 39270 n^4 + 40740 n^3 + 18711 n^2 + 3591 n+205
int(exp(1/((x-a)*(x-b))), x = a .. b)
complexplot examples in the help is limited.
this is a example
c is a fixed,
a is a real number
a is a complex number
plot the locus.
I am trying to substitute an expression that contains hermitian operators where the ordering is crucial. I have tried algsubs and simplify-sidderels, but they both do nothing.
I am trying to substitute;
a + b*c*b = R
where all are defined as hermitian operators in the Physics package.
into an expression;
H = - a - b*c*b
but nothing happens...
However, when I substitute a = R - b*c*b, rather than getting H = -R, I get;
H = -R + c*b - b*c*b
Ok, so for my Analytical Mechanics class, we have a problem that requires the use of Maple, Mathematica, etc to solve. I was able to get a workable solution, but getting a final answer (for initial groundspeed, as I'll describe in a minute) involved a process of guess and check, manually tweaking variables to find a close approximation. My professor's solution did much the same thing. I don't like guess and check, since I'm sure Maple is capable of doing what I need it to do automatically. So I'd like some suggestions on how to make it work. First, though, The Problem:
I am working through the example in maple help,
trying to save a lib (maple library)
I have written several procedures (predefined function).
How do I make them a package?
So I just have to load it with "with(myfunctions):"
then I will be able to use thses functions.
I have had a look at
not so sure if I understand all.
what function should I look it maple help?
Thanks in advance.
