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?

I define a partial repeating decimal as shown in the following example: if you have the decimal expansion 0.1728394877777777777777777777771939374652819101093837... 7 is called a partial repeating decimal.  

Back in 2000 I noticed a pattern in the decimal expansions of sin(10^-n) for growing n. Here is table of some integer n:

n                sin(10^-n)

1 9.98334166*10^-2

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).

Hello....

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

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.

Back in 2000 I published A034948, A036663, and A036664 in Sloane's Integer Sequences, now OEIS.

But today I decided to find the exact values of some such quotients.

1/9801=0.repeating(000

100010203040506070809101112131415161718192021222324252627282930313233

I might be doing something wrong here. But when I ask Maple 17 for the integrating factor of this ODE, it does not match the result if I find the integrating factor directly.

restart;
with(DEtools):
ode:=2*t*y(t)+t^2*(diff(y(t), t))+t^2*y(t)-2*y(t)-t*(diff(y(t), t)) = 0;
intfactor(ode);
simplify(exp(int( (t^2+2*t-2)/(t^2-t),t)));

Why I am not getting the same result from the last 2 commands above?
