Hi,

Below, you will see a serie that I would like to obtain in Maple.  Any way I trie I am stick with Pi.  Any ideas?

Thanks in advance.

I am trying to plot a two variable expression in single 2D plot but have been unsuccessful.

I already have an equation in two variables that is obtained through a lengthy process of calculations:

DEQ = A*D + B*Ne, where A and B are constants, and D and Ne are variables.

I can easily plot a 3D graph of this, but I'd also like to plot what are essentially slices of the 3D graph onto a 2D graph. Actually to plot several slices on a single 2D graph.

I have tried to do the following but have been unsuccessful:

Below is my attempt at a cocktail sort, there are two lines of code missing as i am unsure as what to put there. I think the rest is correct.

Please check and see if you can spot what i need to include.

How do I get a,b,c,d to the function a*b^x*c^y*d^z-x-2*y-3*z  get the minimum with {0<x<1,-1<y<1,-1<z<0}?
Thanks in advance !

Hi

I read a lot of guides, forums and etc, i've been trying to add/remove shiftenters and i've got always the same error. Every parenthesis is checked. Please tell me, where is the mistake?

Hello,

I have problem with Inverse Fourier Transformation. I have an expression S, Maple can't calculate its Inverse Fourier Transform:
 

restart;with(inttrans);

S:=Heaviside(-w)*exp(-(9/640000000*I)*w)/w^2;
invfourier(S,w,t);

 

I have Maple 13.
Thanks for help in advance.

I have programmed a bisection procedure below, and i was just wondering how i would change this into a recursive version of the method. I don't really understand what is ment by recursive?

bisection:=proc(f,X,Y,Z)
local a,b,c,d;
a:=X:
b:=Y:
d:=Z:
while(abs(b-a)>d) do
c:=(a+b)/2:
if sign(f(c))=sign(f(a)) then a:=c else b:=c
fi:
od:
print(evalf((a+b)/2)):
end proc:

Many thanks!!!

convert Arg[I*Sinh[1 + I]]to Pi - ArcTan[Cot[Abs[Tanh[1 - I]]]]

arg(I*sinh(1+I))

arctan(cot(abs(tanh(1-I))))

Hi All,

I am combining two problems I have with fsolve. 

1)  When fsolve finds a solution, it does not distribute the result globally.  So I have to cut 'n paste each result on another line.  Big PIA.  Is there a way to globalize the results?

Dear Maple users

If i have two lists L:=({1,2,5},{3,4,6},{1,2,3}) and G:=({2,1,3},{3,5,1},{1,5,2})

How would i write a procedure to put these two lists into one as {1,1,1,1,1,2,2,2,2,3,3,3,4,5,5,5,6} i now there is a method in maple help but it doesnt meet what i need.

Any help would be appreciated.

I am attempting to get MAPLE to generate indefinite integrals that are of the form:

exp(-k[r^2-a^2*cos(x)]^0.5)

from fundamental calculus principles I might set u = [r^2-a^2*cos(x)]^0.5 which then should yield du/dx = 1/2*(a*sin(x)/[r^2-a^2*cos(x)]^0.5).

Then if my math is correct the result should end up:

2*(r^2-a^2*cos(x)]^0.5)*exp(-k[r^2-a^2*cos(x)]^0.5)/[-k*a*sin(x)]

Hello.

At first, sorry for my poor english.

I am seeking, since a long time, a way to intersect a straight line, horizontal or vertical, and a sequence of plots, which describe a closed figure.In order to calculate the area.

In one way, i want to seek points describe by:

the taylor series of a function

g(x) = f(x + a * f(x)) around a point x = x0 is given as (hoping i am correct)

g(x) = f(x0) + f'(x0) * (x+a*f(x) -x0) + f''(x0)/2 * (x+a*f(x)-x0) + .... ------------(********)

but using the command

taylor(f(x+a*f(x)),x=x0,4)

gievs

f(x0+a*f(x0)) + f'(x0+a*f(x0)) * ....

 something which is different ...

how to get (***********)

Given a list of values L:=[a,b,c...] how do i order the list from highest value to lowest?
