Let be any positive Integer :. Find

Hi, I got a doubtI don’tknow how to make the Runge-Kutta’s and Euler’s method. The Runge-Kutta for thesecond and fourth order. I don’t know how to beginning the algoritms, I needsome help. Thanks.

Now I compute the integral 

0<int((abs(c-x)/x)^n,x=a..b)=int((c-x)/x)^n,x=a..c),symbolic)+int((x-c)/x)^n,x=c..b)

assuming c>0,b>c,n>-1.

As it is not possible directly, I split this apparently real integral in two parts. Both parts are real for n>0. Look, what's happens!!!

> Za:=simplify(int(((c-x)/x)^n,x=a..c),symbolic) assuming a>0,c>a,n>-1;

I executed a Jacobian function as follows X:=Jacobian([a,b,c,d,e],[y[1],y[2],y[3],y[4],y[5]])
a,b,c,d,e are initialized expressions/equations and
y[i], i=1..5 are the variables and I got the result below

Hello all,

As in title I am really bothered with result in floating number obtained from laplace(expr, t, s).

I have a target to laplace and the laplace() gives me result with floating numbers.

(ex. laplace(diff(diff(f(t),t), t), t, s) = laplace(s^2. * laplace(f(t), t, s) : the period after 2 is annoying)

How can I avoid or do some conversions to kill the periods?

When I do integration and differentiation, even of the simplest functions, it gives me incorrect answers. What could I have done wrong? Just to mention I recently installed a licensed copy on my computer. 

when i open a new worksheet its indicates it as untitled worksheet number 11. whcih means i have 10 previous untitled worksheets. where are these stored. i can not find them in the maple folder?

Hello,

I have quite big problem with results processing from dsolv. 

reseni := dsolve(numeric, number = nclas, procedure = PopBal, start = 0, initial = inicon, procvars = dvars, range = 0 .. tend)

If I want a results from "reseni" in "tend" 

results(tend);

I got this one:

[t = 5., n[1](t) = 0.803965539772492772e-1, n[2](t) = 0.108666500575795332e-4,.........]

Now i dont know at all how I can work...

Hello!

I'd like to create a table in Maple showing the values for multiple functions.

For example, I've three functions, y1,y2,y3, and I want to create a table for different values of my functions.

Is there a straightforward way to do that in Maple?

Many thanks in advance!

Hi:

I have a problem in calling a procedure. The problem that the code is working perfectly when I use it without precedure, but when I wrap it with a procedure and call the procedure I get like this problem

hi

I have two unkhnown matrices. I intruduce one of them with fill:

The built-in Histogram command in the Statistics package only creates a Histogram from raw data, unfortunately. There is however a big number of situations, where you only have grouped data with intervals and their associated frequencies (probabilities) and want to plot the Histogram. Suppose that the intervals are of equal width and (indirectly) are specified from a starting point x0, a column-width named 'width' and the number of intervals given by n. Suppose the frequencies...
