Hi:

I would like to ask maple to "recognize" a Fourier transform in a (possibly complicated) expression.

Maple defines a Fourier transform in this way:
convert(fourier(f(x), x, k), Int);

So if f(x)=1 we should get something that is proportional to Dirac(k), which we do:
fourier(1, x, k);

...but given an expression
exp1:=Int(exp(-I*x*k), x = -infinity .. infinity);

... how would tell...

Error:

Please help?

Now it's division by zero, help...

Bonjour,

Je cherche une méthode éfficace pour résoudre le système d'équations polynomiales suivant :

with(SolveTools):
> PolynomialSystem({f0,f1,f2,f3,f4,f5,f6},{alpha,lambda,mu,nu}); 

# avec les fi ci-dessous :

f0:= (1+mu+nu+lambda)*alpha^3*(1+mu+nu)*(mu^2-2*mu*alpha+2*nu*alpha*mu+2*mu-2*nu*alpha+2*nu*alpha^2+alpha^2-2*alpha+1+alpha^2*nu^2)*(-lambda*alpha^3+3*mu*nu+alpha^2*lambda-lambda+3*nu*mu^2+3*nu*mu^2*lambda+l...

 

 

I tried this on maple:

eps1 := [0, 1/5, 2/5, 3/5, 4/5, 1]:
start1 := 2.3:
base1 := 1.1:
for i from 1 to 6 do
R := start1*base1**0:
points1[i] := [R, evalf(eval(mH, {M=1, r=R, epsilon = eps1[i]}))]:
for a from 1 to 20 do
R := start1*base1**a:
points1[i] := points1[i], [R, evalf(eval(mH, {M=1, r=R, epsilon = eps1[i]}))]:...

Good afternoon sir,

 

I am getting the reslut around a=22 degreees  instead of 33 degrees when solved the following Trigonometric equation

A sin α cos α + B sin2 α − C cos α − E sin α = 0,

where A = lsin β1, B = l cos β1, C = (h + 0.5D) sin β1 − 0.5Dtan β1,
and E = (h + 0.5D) cos β1 − 0.5D.

Good morning sir,

 

Please help me out to fit the Gompertz growth model using Maple.

 

with thanks & regards

I am trying to finish up an assignment but this problem is giving me issues. The problem is to find the first positive value of x=2sinx to within 10^-5

I used the following code

 

with(Student[NumericalAnalysis]);
f := x-2*sinx;
                           x - 2 sinx
a := 1;
      ...

Hi. I have two problems connected to Physics package and complex numbers. The main problem is undesired decomposition of a complex value t into Re(t)+I*Im(t).

The first problem is connected...

Hello....

how to convert decimal to binary??
for example [10, 3,90,6]..
how to convert this number into binary??

I have a list contains the triagles with in each triangle has mesure of the angle AOB equal to 45 degrees. Now I want to select four points in list so that they lie on the graph of the funtion y = (ax + b)/(cx + d), where c <> 0. This is the code which I make the list.

I want to use Maple (dsolve command) to solve this problem, how do I input the command? Part (a) is enought.

I have tried the command, but Maple says "Warning, for {u(t)} arbitrary the system is inconsistent".

Thank you very much for your help.

hi maplefriends, i´m trying to solve a piecewise funtion, and gold is find the maximum and  location, for that i use de package Maximize.unfortunately the result i have is the local maximum, can anyone show me, how can i do that? >  >  Download maximize_abs.mwbest regards
