Below and above the iterators, there is a graphic with numbers rotated in all directions.  I am thinking it is based somewhat on what I have done here http://www.mapleprimes.com/posts/97195-Wordle-In-Maple

How did they get the rotations in Maple?

In functions such as fsolve, there is an optional parameter that allows one to specify the interval to perform the function on. Additionally, sometimes, if a solution is left out, one can specify an interval to search on to obtain the missing solution.

How does Maple determine the interval to search on if this is not specified?

(Additional Question - you don't have to answer this)

Ultimately, I am asking this question because I have a function for Newton's method; however, it requires an interval to run. I have read that fsolve uses Newton's method, so I am curious how to automatically select such an interval. Does anyone know how to implement such a thing?

Hi,

Let, fixed an integer i and 1<=j<=2^{i}-1, for each x and y in [0,1] let the following mapping

Then, with the above procedure we can obtained, for a fixed i, all the mappings for j=1,...,2^{i}-1

However, How can I to evalute the "components" of the above procedure? For instance, I can not to compute CreaF(2)[1](0.35,0.465) (i.e., the first function in the "vector" CreaF(2), in x=0.35, y=0.465). 

Thanks very much for your time.

hi everyone..i would like to ask,why do we need to type in (101-100λ) in our maple program..why do we need the continuation..thanks in advance for answering..

how to convert baby monster group into permutation group and iterate baby monster to display all permutation group?

Hello,

I have a sequence of functions :  solution[i] , i = 1..n

I have a sequence of times:          Time[i], i = 1..n+1

I need help to plot in the same graph:

 plot(  Sol[1] , t = Time[1]..Time[2] )  

 plot(  Sol[2] , t = Time[2]..Time[3] )  

 plot(  Sol[3] , t = Time[3]..Time[4] )  

etc...

plot(  Sol[n] , t = Time[n]..Time[n+1] )  

Thank you

Hello,

I got two problems creating a 3d-plot. First, as the title mentions, I want to cut out a distinct interval from my 3d-Plot.

For example when the graph is displayd from -y_max to y_max but I just want it to be shown from -y_max to -5 and from 5 to y_max again.

I also got a second question:

Another thing I want to do with this graph is redefining this axis with a parameter which is directly dependant from it.

Like for example I want to redefine the "y" axis with a" k" axis with k=y*2, so that in the end I have th

Sometimes this happen to me.

Hi dear experts

I'm wrote a complicated code for stress computation and define each component of stresses for n layers in a n dimension array.

for example (for srr component):  srr[1]:=f1(r,theta) , srr[2]=f2... , ..., srr[n]=fn(r,theta)

n is defined in the start of worksheet and is no. of layers!

so, i want to plot all of layer functions in a same coordinate plane.( beacause they are discontinuse and i want show that)

note: display command don't do that and plot them in a table form! :(

how can i do that?

thanks for participate.

My question is related to changing the plot size and modifying the number of ticks.

For example, I am plotting y vs. x, and x is from -1.0*Pi/2..1.0*Pi/2. I want to modify the plot size with size=[h,w]. If I have three ticks in x-axis if I change to small width, then the number of ticks is decreased. How can I force it to have the certain number of ticks? Also, why if I set view=[-1.0*Pi/2..1.0*Pi/2,0..1] then the -1.0*Pi/2 disappear if the width size is small. 

Thanks,

Hello people in the mapleprimes,

I have a question, so I hope someone give me answers to it.

I calculated for the solution of the follwing differential equation.

restart
b:=diff(y(x),x)+a*y(x)=f(x);#where a and f(x) is not specified.
dsolve(b,y(x));

subs({f(x)=exp(x),a=2},%);where f(x) and a are specified.

c:=value(%);

The solution of the above was

y(x) = (1/3)*exp(x)+_C1/(exp(x))^2,  (A)

where please note that the second term takes

the form of fraction _C/(exp(x))^2.

On the other hand, next I calculated the following differential equation where f(x) and a are specified from the start.

restart
d:=diff(y(x),x)+2*y(x)=exp(x);

dsolve(b,y(x));

Then,

y(x) = (1/3)*exp(x)+exp(-2*x)*_C1  (B)

was the obtained solution.

Each (A) and (B) are the same substantially mathematically. But, for Maple, the variable powered to minus brabra

is not the same as one over variable powered to brabra, so that (A) and (B) takes different forms, and maple will see them 

different with each other.

  Surely, with algsubs, algsubs(_C1/(exp(x))^2=exp(-2*x)*_C1,c) transforms (A) to (B).

But, I want to know whether there are some other ways than that  to modify (A) to (B).

If there are any good ways for it, I will be happy if you teach them to me.

Thanks in advance.

Hi, I am new to maple, but I think that my question should be simple.

I have a matrix where each element is an expression. I want to compute the matrix for different constant and to save it without crushing the previous matrix. 

If the file that I joined, I have a first part where the constant are defined. In the second part the expression of the matrix is defined. Finally, I compute each matrix with different constant. Each results is called C_p0, C_s0, C_g0. When I called them back, only the last matrix computed remains.

I would like to be able to save each matrix to performed operation on them later.

Thank you.

Hello,

In the context of solving mechanical constraint equations, I often need to simplify trigonometric equation. In mathematica, the FullSimplify function makes the simplification I need. But, i'm using Maple for a long time and I would rather contnue my calculation with Mathematica.

May you see if so can help me to simplify this equation ?

Here the equation I would like to simplify with Maple :
