People:

I wrote a Maple 15 worksheet containing a function that calls two other functions defined earlier in the worksheet. The main function didn't work, so I replaced one of the functions that was called, by cut-and-pasting its definition into the main function. This is obviously inconvenient because I want to alter the function that I cut-and -pasted and whenever I do it I will have to cut-and-paste again. It also detracts from the...

Hello,

I have created a test document to check an equation and I would like to feed a range of k values (ranging from 0 to say 512) in increments of 1) to the main function, and then plot the result as a graph of Zuncomp (y-axis) vs k(x-axis).

I can verify the values of the function by typing say Zuncomp(0) or Zuncomp(10) etc but how do you run this so that you do Zuncomp(k) to read all values of k and generate the output to plot?

Hi

In trying to solve:

a := diff(u(t), t$2)+(p^2-I+t^2)*u(t) = 0;

I get the following solutions,

sol1 := u(t) = _C1*WhittakerM(-1/4-(1/4*I)*p^2, 1/4, I*t^2)/sqrt(t)+_C2*WhittakerW(-1/4-(1/4*I)*p^2, 1/4, I*t^2)/sqrt(t)

It should be possible to expand these into parabolic cylinder functions and but im not sure how, i would appreciate any help.

thanks

Hi everyone,

I am trying to understand how can I create a function based on the differentiate of a matrix.

For instance: And I would like to create the matrix FF based on the derivative of F with respect to x and then be able to use FF and a function.

I tried to combine, unapply, map and diff but I can't reach what I'm looking for.

Hi,

I want to create a tangent function.

I know that you can create tan(x) but how can you create the tangent function when the solutions are only:

x in [0.19740;0.91510[ union [3.3390;4.0567 ?

Another explanation:

How you can graphically show the valid values of x in this inequality?

0.2 ≤ tan x < 1.3Best regards

Hi guys. I need to do a Runge-Kutta method to solve two equations and I'm having trouble at using functions. My program is as shown below:

restart; A := Matrix();

dt := 0.1e-2;

diff(x(t), t) := v;

diff(v, t) := a(x(t), v);

xo := 0; vo := 0;

for i to 1000 do

xn := xo+v.dt;

vn := vo+a.dt;

dx1 := vn.dt; dv1 := a.dt;

dx2 := (vn+(1/2)*dv1)*dt; dv2 := a(x(t)+(1/2)*dx1, (1/2)*dv1)*dt;

dx3 := (vn+(1/2...

Good day, dear Friends!

I'm trying to find real positive roots of equation

with Maple 16.01.

One can easly verifies that this euqation has at least two positive real (integer) solutions: at x=5 and x=10,

but Maple function

I would like to do the following procedure from a basic concept, but I can't figure out what I'm doing wrong (sorry for that, I'm a beginner). I have tried to look up some more information about procedures on the Help menu with no success. Here you have what I'm planning to do:

Considering the following function (which approximates the cosine function):

aprcos:=(x,n)->add((-1)^i*(x^(2*i)/(2*i)!),i=0..n)

I would like...

I have

f(x,y)=x y+x^2+1

and

g(t)=(2 t, 3 t).

I want to obtain the function (f o g)(t) as a real-to-real one variable function.

What I tried:

f:=(x,y) -> x y+x^2+1, it's ok;

g:=t -> <2 t, 3 t>, it's ok.

But f@g returns f@g.

How it would be possible to obtain f o g ?

My mathematics computation relies on a loop.

That loop is heavy and takes very long time to finish.

I try to split some undetermined functions outside the loop so that the work inside the loop will be easier.

I don't know how to use proc or module. Is there any tutorial that can help me as a beginner on this part?

Basically i need maple algorithm that enables user to call a user-defined function from another function.

And also how can...

Dear Sirs,I am a post-doc working on the university and I am dealing with elliptic integrals together with Maple, nowadays. I am using for my computations en EllipticK(.) function and I need to know how this function computes its exact values for a given parametr of an elliptic modulus. Does it use some kind of a series(how does it pertinently look like?) or is it tabelated and consequently interpolated? Please, will you be so kind and could you give...

Assumption:f(x)=x^2+2x

how to solve f(x+1) according the assumption.

this question is going to be asked has been done several times by me but no answere is sent,but i do it again:

f(x)=sqrt(x+1)→domain(f):[1,+∞),range(f);[0,+∞)

how to solve them at the maple15

Some calculus problems are worked out with the differential formatted as a function prime (f', G', etc.). How do I enter a function with the prime symbol so that Maple will treat it consistently? I recall entering f'(x) once in the legend of a Plot. The legend, as output, was in 2D format d/dx(f(x).

Another variation on my question is this: If I enter diff(x^2,x), or d/dx x^2 in 2D Maple, and calculate, I get 2x. If there a way to enter f'(x^2) to get the derivative?

I have the function f(x) =

and x <= 20

How would I specify it in maple and then I have to take the derivative and find the critical points. I am so confused.
