Can you help me please ?

I'm having a lot of problems figuring out how to use Maple. I've watched all of the tutorial videos but they arent much help and there are no step by step directions, or templates, that show you how to solve the problems for my Linear algebra class. Here is the problem:

2x-3y+4z =-12

x-2y+z=-5

3x+y+2z=1

Could someone please quicky walk me through the steps needed to solve this problem? Thanks a lot.

Hi there, I got a set of discrete Data as functions of 4 variables (x1,x2,x3,x4) . I would like to interpolate the data and then get a continuous function f in terms of (x1,x2,x3,x4). Finally I would like to get the partial derivative of f wrt x2. How can I sort out this? x0:= 1/2: s:=x->x^2: sol:=(x2,x3,x4)->dsolve({y''(x1)-(x3^2+s(x1)*x4^2)*y(x1)=0,y(x2)=exp(-x2),y'(x2)=1/2},numeric,output=operator,range=0..x0): g:=(x1,x2,x3,x4)->eval(y(x1),sol(x2,x3,x4)): g(x0/3,x0/3,10,1); dx2:=1/1000: Data:=(x1,x2,x3,x4)->[seq([x2+i*dx2,g(x1,x2+i*dx2,x3,x4)],i=-3..3)]: ???

Hello, Can you set Maple to use degrees instead of radians instead of converting all the time? I have tried to search for it, but I did not understand those methods that were written. Greetings, Jonas

Good Morning Everyone,

Would anybody help me in the following if statement. What I would like is to compare the value of Az with the allowable, if it is less than allowable, I would like to print "O.K" , if not I would like toprint "N.G". In Maple I'm getting an error message, invalid terms in product. Please Help.

if (Az < 0.25*mm) then print "O.K" else print "N.G" end if;

 

Hello there, I can plot a set of data into a boxplot, but I am unable to plot a boxplot directly from a set of descriptors including quartiles, minimum and maximum. Say I have these data: 3, 12, 13, 16, 20 - 3 being the minimum, 20 the max, and 12,13,16 are my quartiles (lower, median, and upper). Is there a way to plot these into a boxplot? a) Make a box plot of the results for each of the two classes and describe the difference between the two classes of performance test.

I would like to declare spin states; spin up (alpha) and spin down (beta)

such that they form an orthogonal basis not necessarily using Dirac Ket notaion.  I am using the Physics package and Linear Algebra

When I try to use the Dirac Ket notation, I have noncommuting issues with the Cartesian basis

Cart := Vector[column](3, [Ket(X), Ket(Y), Ket(Z)]);

Spin := Vector[column](2, [Ket(alpha), Ket(beta)]);

Hi pro, I have some problem with Maple.

Now I use Maple 12.

First

I want transfer this mathematical formula

> sin(q[1])*(sin(q[2])*cos(q[3])+cos(q[2])*sin(q[3]))

to

> sin(q[1])*sin(q[2]+q[3]);

how to do that. Can i use any command ?

Second

When I type this command

> A:=diff(sin(q[1](t)+q[2](t)),t);

and now I want derive with variable dq[1](t)/dt then how do i ?

 

I have done a lot of research and simulation when it comes to trailing stop losses.

I have managed to get very nice results but only through theoretical reasoning

and simulation. However simulation is not as "pure" as manipulating equations.

What I have not managed to do so far is to manipulate the PDF to get an probability

that the trail stop is going to be triggered for a specified normal distribution (mean, volatility)

and trailing distance.

 

I have a rather simple equation describing a predator prey model  p=900+c*e^(t/2)

I want to plot the equation for various values of c.  How do I set maple to plot it? 

am try to integrat the following
 

int((z-x)f(x), x=L...z-1)
 

where f(x) is an undefined PDF, L is the lower bound H is the upper
bound.  The results should look like this
 

(z-1)F(z-1)+int(F(x), x=L..(z-1))  using integration by parts
 

Similarly  I want to integrat
 

int(xf(x), x=z..H) again, using integration by parts the result I am
lookig for should be
 

xF(x) - int(1-F(x), x=z..H).
 

Could any one see what maybe the problems pls?

 

Could any one have a look at my results pls, don't know why I couldn't get the right results!?

I have several plots need to be dislayed together. They are not assigned color property before hand. I knew that I can use display command to plot them together. But I wondered if I can plot them in different colors.

So I'm new to Maple and I have a homework problem that says:

"Write x^3+x^2+x+1 in terms of powers of x-1 using the taylor command."

Honestly I have no idea where to even start, any help would be awesome.

Thanks,

Andrew
