I have to solve this question

Find d^2y/d^2x and d^3y/d^3x if y is defined implicitly by y+sin(y)=x

So far I have 

f:=y+sin(y)=x;

implicitdiff(f,y,x$2);

and

implicitdiff(f,y,x$3);

both of them spit out answers, but am I doing that right for the question that is asked?

Hey, how do I find the maximum/minimum values of f(x) on maple?

Hi,

I want to solve a small system of quadratic equations using Maple. There are 4 unknowns and 4 equations.

The solve function has a problem with that kind of a system (I'm sure that this system has a solution).

Is there a method of solving that kind of systems of equations in Maple ?

Thanks in advance.

In my maple 16 the following is returning FAIL. Why ? and what is the correct way to do the following.

restart:

assume(n::posint):

is(n^2<=2^n);

Regards!

I want to be able to check an answer using Maple. Say perhaps I have a question such as "Find d,e,f such that f(x)=dx²+ex+f has the properties f(0)=4, f(3)=7, f(-2)=18".

The question is completely theoretical as I don't want to use the same question that I have been given myself and be accused of cheating, maybe the particular features that I have chosen are completely absurd.

My question is how would I go about using Maple to find/check that I have the correct values of d,e and f?

Find a(n)of sequence3,9,18,54,63,...   (n=1,2,3,4,...) ,

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

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?

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