This is my first time using Maple - so I don't even know where to start... Hopefully I can make this clear... example problem: f(x) = 2.3x g(x) = ax^3+bx^2+cx+d h(x) = px^2+qx+r l(x) = kx^3+mx^2+nx+s I was able to find the correct syntax for Maple to calculate the first and second derivatives of the functions above. Now I have to write out a system of equations using the original functions and their derivatives...once I have the system of equations then I need Maple to solve for each variable...what is the proper syntax for all of that? Also, for Maple to calculate the derivative I used "diff(f(x),x)" and "diff(f(x),x$2)", so how do I get those derivatives into my system of equations?

Hello, Earlier this year I reached an impasse with Maple's numerical integration package over the need for a high-resolution (say 50 or more digits) evaluation of multiple integrals for a Bayesian statistics application. An integral such as sqrt(1.+4.852800000000*chi[2]^1411+5.887416960000*chi[1]^200+4.852800000000*chi[1]^100+5.887416960000*chi[2]^2822-21.48043392000*chi[1]^100*chi[2]^1411) over a rectangular range like chi[1]=0..0.9999,chi[2]=0..0.9999999 would return unevaluated. Infolevel[`evalf/int`] explained that the methods available in Maple would not return the required precision. But the problem persisted even when I swallowed my pride and settled for 12 digits of precision. Stuck as I am, I haven't even tried to present the problem to Maple in higher dimensions.

i'm curious if exist any possibility to make a procedure like

myproc:=proc(x,y)
.
.
.
endproc

and then assign to it a typesseting rule which display statement

myproc(x,y)

to

x (some symbol) y

thx for any advice...

hi everyone,
i'm trying do a tamplate for solving school problem. I need only input some variables at begining and it's should give me whole solution. But i need to print it so i have to use this layout style:

i have:
f:=y=x+5
then i use:
subs(x=2,f)

i wanna have inline form
y=x+5=2+5=7
but i can get only
f=y=x+5subs(x=2,f)=7
this is just for examle of layout i want to get but i don't know how...
if i turn off input the subs(x=2,f) dissappear but gap still remines..

btw does exist a statement by which can i control if expreson is inline or not?

How can I do Laplace transform of Jacobi elliptic functions (e.g. SN,CN,DN or Theta) using Maple? The simple formula >laplace(Jacobi SN(t,k),t,s); does not work. The more complex formula int(exp(-p*t)*JacobiSN(t,k),t=0..infinity);does not work too. May be Maple numerical solution exists? Jane.

I have a Matrix (M) and want to extract the actual equations from the following M.x=x; where x is a vector of variables that I want to solve for. I would like to be able to extract the actual equations (the values for M are determined elsewhere), for example, 3 x1 + 4 x2 + 2 x3 = x1. How can this be done in Maple? Thanks. Brian

I am a newbie to Maple, i have learnt Maple for several days.In Matlab i can easily declare a row vector t=0:0.02:0.5 (from 0 by 0.02 to 0.5) but in Maple i can't. I tried using "for" loop but i could not insert into a vector. How can I write a vector like that ? Please show me.Thanks a lot.

>e1r := -1.5; > e1i := 12.455; > e2r := -.022269812; > e2i := .25368881; > E1 := e1r -I*e1i; E1 := -1.5 - 12.455 I > E2 := e2r -I*e2i; E2 := -0.022269812 - 0.25368881 I > nz1 := RootOf(E1*NZ^4 - NZ^2*(2*E1^2) + E1^3 - E1*E2^2=0,NZ,index=1); Error, (in content/polynom) general case of floats not handled ok so what is wrong with this? its all simple equations and complex floats, the syntax for rootof looks correct...

I wanted to solve a differential equation and followed the examples in Maple manual exactly: ode := {(2*t*x*q+x-4*t*x^2*(2*y(v)-1))*(diff(y(v), v))-1 = 0}; ic := {y(0) = 1/2}; soln := dsolve(`union`(ode, ic), {y(v)}); But I got neither results nor error informations. Does it mean, "ode" has no solution? In such case, how can I get some tips from Maple? thanks a lot.

I have a problem with a sentence that I have. I don't know whether it is a formatting problem or problem with the statement itself. I'm trying to say something like this (if it makes it less abstract, I'm trying to formally define a Sudoku puzzle). For any set S and function F that maps the ordinal set |S|^2 to |S|, there exists a set T which is a subset of S^|S||S||S| such that any element of T Tabc is equal to the empty set iff c !=F(a,b) First of all, theres a couple issues with this. |S| is the cardinal of S, but for convenience I also use it as an ordinal set. Second, as I started typing this I saw that I do not have the necessary statement for all Tabc which are members of T. How can I correctly input this statement into Maple?

I was wondering if anyone can recommend a good (free) text editor for writing Maple source code. I am writing some programs and thus far I have just been using Notepad, but automatic syntax highlighting and indentation would be nice to have. Thanks!

I am trying to use maple to find the limit of a subsequence, but what I've tried hasn't worked

For example define . Then using maple

Hello,

Im meant to create a program to compute inverse tan - tan(^-1)(x)

to a given accuracy. They gave examples in class of how to do it for

1+1/2+1/3+...
1+1/2+1/4+1/8+...
sin(x)

like to 8 decimal places or whatever.

here's what i got on my screen.

http://kr.cs.ait.ac.th/~radok/math/mat6/calc6.htm
This sort of has an explanation on how to get the taylor series for inverse tan. basically i was gonna try to copy and paste the output for the sin(x) eg. and just swap the taylor series to see if it would work.

ANY HELP WOULD BE APPRECIATED.
OUTPUT:

> sum_ex1:=proc(x)

Hi,
Can someone tell me how to solve an IMPLICIT first order ODE? That is, an eqn. of the form F(x,y,y')= 0 where we cannot seperate the term y'. An example will be helpful.
Thanks.
D.O.

I have the following code snippet which uses solve to get the 4 solutions to a quartic equation. In my application I must know which solution is which, for they each have a specific placement in later calculations. I know that most of Maple's datasets use memory address as their method of sorting, and therefore each run can give a different order to the results. Is this also true for solve? I need to know a way which the order of the solutions will always be constant. (sorting by returned value will not suffice) WaveEQDet := proc(layer,eV) local E1, E2; > E1:=Epp1(layerelementtable[layer], eV);
