The question is“fsqFsHn sGGousG” is the result of applying a Caesar cipher to its original title. A 53-character alphabet
consisting of all the upper-case letters, a space, and all the lower-case letters
was used; consequently the space in the middle might or might not correspond to a
space in the title. Determine what the original title was.

Hi,

I'm having some trouble with finding an algorithm to check  which interval , the element 'x' is part of.

for instance : say I want to know if x belongs in , A := [ a, b ] or B := [c,d] or..... 

How does one write the proper code for such a problem?

Thanks a lot in advance,

Yoeri.

 

How to solve the boundary value problem for this system of ODEs. I used solve DE Interactivly but that failed to get me an answer.

 

ODEs:=4/5*F(x)*T(x)'-1/5*F(x)'*T(x)=T(x)'',  3/5*F(x)'^2-4/5*F(x)*F(x)''=-F(x)'''+T(x)

BCs:=F(0)=0. F'(0)=0, F'(10)=0, T(10)=0, T'(0)=-1

 

Thanks in advance,

 

Hello, I have a script in Maple that generates a function that I want to plot for many different values of one of its paramters. I was wondering if there is a way to construct a program that will make these plots for a number of different values for that parameter, and save these plots as JPEG files each time. for example, I want to be able to do this: 1- epsilon = 0.001 2- run program that generates function 3-save the resulting plot as a JPEG image called epsilon001 4- epsilon = 0.002 5 - run the program again ... and so on. Is there a way to do this in Maple?

  Hi there !   The attached worksheet has exciting animations made entirely through equations that we are familiar with from high school. The worksheet has an animation of a bouncing ball. No longer do you need a $500 camera to take photos to illustrate the sequence of motion - because Maple has that feature built - in !   Feel free to ask questions or add your worksheets to further develop mathematical animations.

Hello everybody. I was wondering if I can do this with maple: Consider the ideal

Hallo,

I am new with Maple and encountered the following problem.

The following code opens Excel Workbooks (Test1.xls, Test2.xls,...) and stores the values in the
variable data. data is then used to perform a simple operation (second and third for statement),
which calculates curvature.

The string below was encrypted using an affine cipher on the 27 letter alphabet
“ abcdefghijklmnopqrstuvwxyz” (there is a space in the 0th position.) Decrypt it.

I have rearranged a complex impedence equation into the form of a complex number 

z := R*omega^2*C^2/(omega^2*C^2+R^2)+I*(R^2*omega*C+omega^3*C^2*L+R*omega^2*C^2)/(omega^2*C^2+R^2)

(Affine cipher)This phrase follows the the typical pattern in English where there are (almost) as many spaces as words and the letter “e” is also very common. The string  fmw segjaweoouanerj a ceyqrype aswaheoaqbrqabeafrua eeaojerf afmjeayperjpu  was encrypted using an affine cipher on the 27 letter alphabet, there is a space in the 0th position. Can anyone give some hints how to decript it by first solving 2 equations of the form ax+b mod c
 

I am trying to plot the ouput of a procedure as oulined below:

Hi all,

You will find in the attach worksheet, an example where the solution of an ODE, solve by inttrans, does not agree with the solution of Maple found trough dsolve.  Why they do not agree.?

I have an ODE containing different orders of differentiation of f1(x), f2(x) and f3(x).

> with(PDEtools):

> difforder(ODE);

or

> difforder(ODE,x);

gives the order with respect to x but I need a "COMMAND" doing below,

> ODE:=12*diff(f1(x),x$5)^(7/2)*diff(f2(x),x$4)^9+12*diff(f3(x),x$3)*diff(f1(x),x$2)^9;

> COMMAND (ODE,f1(x));

5

> COMMAND (ODE,f2(x));

4

> COMMAND (ODE,f3(x));

Hi,

i have a minor issue with a plot, have a look.

restart:
 f:=x->piecewise(x<-1,0,x<0,-1-x,x<=1,1,0);
 plot(f(x),x=-2..2,discont=true);

Where are the plot lines on the x axis for x<-1 and x>1 ?
