Having a recurrence relation of the form:

f(n)*c_{n+1} + g(n)*c_n + h(n)*c_{n-1}=0

with coefficient functions f,g,h is it possible to convert this into a matrix of dimension N+1

thus if the sequences c_n are the coefficients of a series sum_{n=0}^{infinity} c_n x^n I'm only interested up to order N of the series

e.g. N=2

n=0: f(0)*c_{1} + g(0)*c_0 =0

n=1: f(1)*c_{2} + g(1)*c_1 + h(1)*c_{0}=0

n=2: g(2)*c_2 + h(2)*c_{1}=0

I need help coding the insertion sort algorithm in maple 17. So far, I have the following ..

Good morning Sir,

The output of Gompertz Model is showing exponential decay values but it is stated that

it is on of the exponential growth models. Please clarify this ambigity. The following problem is one such example

Fit a Gompertz growth model to the following data

Hi, again:

Is there a way to connect Maple with Sqlite?

Thanks in advance

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...

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.
