Hello, I have been trying to complete a Maple homework assignment for my Caclulus class. I have been stuck on several problems for several days now and I was wondering if anybody could help me. Here are the questions on the assignment that I am stuck on. I know how to do these problems by hand, but I can't seem to figure out the roper commands to do them in Maple4. Given r(t)=(tsin(Pi(t)))i+(t)j+(tcos(Pi(t)))k over the interval [-2Pi, 2Pi}......    a. Find (dr/dt...

Greetings to all. I will keep this brief and to the point. I would like to point out a certain deficit in the integral transform package. I have recently been calculating some Mellin transforms at this link and the base functions are of the following type.

g := (p, q) -> 1/(x+p)/(x+(p*q-1)/q);

Now to see the deficit here are some Mellin transforms that...

 I obtained a count of 7 with the command: stirling2(4,2) . How do I get a list of the 7 partitions? Thanks.

I just wanted to remind everyone that this quarter's Möbius App Challenge closes Sept. 30.  This quarter's prize is an iPad Prize Pack, which looks very cool but sadly, I'm not allowed to enter.

To enter the contest, all you need to do is:

1) Create an interactive App in Maple

2) While in Maple, log-in to the MapleCloud through the MapleCloud palette.

3) Click on the Send Document to the Cloud button

When upgrading from Opensuse 12.2 to opensuse 12.3 with an nvidia graphics card I got some strange behavior.  It appears that something in the old maple configuration files was causing the trouble.  To eliminate the problem I  deleted the .maple and .maplesoft directories.

 

If you have some serious configuration information, you would need to save that first or track down exactly where the error ocurs.

hi all..

i m solving a system of four coupled differential equations using bvp[midrich] technique on maple..

i have two questions..

1). is it possible to calculate the numerical data using bvp[midrich] instead of graphs?

2). there is a physical constant "A" in my second equation..can i compute its numerical values while fixing all other physical parameters of my equations...

If a, b and c are the roots of the equation x^3-x^2-x-1=0.
Find S=(a^2014-b^2014)/(a-b)+(b^2014-c^2014)/(b-c)+(c^2014-a^2014)/(c-a)

Today, I was working on a problem in the class which said:

if f(x)=ax^2+b, x<=1 and 1/x, x>1; then find the values of "a" and "b" such that f'(1) be defined. I checked it to be continuous at x=1 first and so I got a+b=1. Secondly, I wanted to get another equation, so I checked the differentiability of the function by the definition of derivation at x=1, so:

[> f := x-> piecewise(x <= 1, a*x^2+b, 1 < x, 1/x);
> limit((f(x)-f(1))/(x-1), x = 1, right);

I have a set E of linear equations in variables x[1],...,x[8] (which I created with X := Matrix(8,1,symbol=x)). I now call

 

> solve(E);

I get back something like

 

x[1] = x[2]-x[3], x[2] = x[2], x[3] = 5, ...

 

I would rather like to get

 

x[1] = t[1] - 5, x[2] = t[1], x[3] = 5, ...

 

back.

 

How to do this? I do want to use the solve function (not LinearSolve et.c.).

I'm supposed to do the following. I tried to ask my teacher how I could go about doing it and she told me to just figure it out. I am supposed to find the linear and quadratic approximations to the function f at x=a. Then, I'm supposed to sketch the graph of the function and its lienar and quadratic approximations.

The linear approximation is:

P₁(x)= f(a) + fprime(a)*(x-a)

The quadratic approximation is:

P₂(x)= f(a) + fprime(a...

I have that problem that I am trying to solve the following equation explicit:

TY = RootOf(6.750969101*10^26*_Z*1000^(9/59)*800^(41/59)-1.015701668*10^27*1000^(50/59)-1.189275761*10^27*800^(50/59)+1.103397224*10^26*_Z*1000^(32/59)*800^(18/59)-7.457053114*10^23*3^(1/5)*1000^(41/59)*800^(50/59)*_Z^(4/5)*sqrt(12500)*4^(19/20)*(800^(9/59)+1000^(9/59))^(1/50)*(702.222720*1000^(9/59)+976.508160*800^(9/59))^(4/5)-7.457053114*10^23*3^(1/5)*1000^(50/59)*800^(41/59)*_Z^(4/5)*sqrt(12500...

Can maple in any way simplify this any further?

-(1/4)*m*omega*sin((1/2)*omega*T)*(2*cos((1/2)*omega*T)^2*xa^2+2*cos((1/2)*omega*T)^2*xb^2-xa^2-2*xa*xb-xb^2)/((cos((1/2)*omega*T)^2-1)*cos((1/2)*omega*T))

I've tried simplify, radnormal, combine but am wondering why maple does not convert for example the denominator in sin(omega*T) 

How do enter and use the notation of a step function (u(t-3)-u(t-4) in maple to use in calculations? thanks

Hi,

I wondered if you would be able to help.

I've set up a for-loop and while-loop that substitutes values of j and k into a given function

I want to get the answer for every right for example right[1], right[2]..but this code give the answer for right[1]nd right[6] only..

 

 P := array([[1, 4], [2, 3], [3, 2], [4, 1], [6, 5], [6, 1], [6, 2], [5, 3]]);

j := 1; k := j+2; Fold := 0; Fnew := 1; counter := 0;

 for...

I think Maple is missing some lines and significant points. Here I leave another contribution to the possible implementation of a new algorithm to draw the circle of Taylor.
