Hi

 

how can i do this in maple

 

if(a>b>c) then 4

 

or maybe if(a>b) and if(b>c) then 4

All:

This should be simple but I am clearly missing some of the nuances - can you please help me see what I am doing wrong?  I would like to solve 2 eqns in 2 unknowns:

eq15 := Kzeff15 = (Kvr*Kz15)/(Kvr+Kz15);

eq33 := Kzeff33 = (Kvr*Kz33)/(Kvr+Kz33);

Kz33 := (3.3/1.5)*Kz15;

Kzeff15 := 150612;

Kzeff33 := 253629;

soln_z15 := fsolve ({eq15,eq33},{Kvr,Kz15});

 

 

I am currently running Mac OS 10.5.2. (Leopard) Is there any version of Maple that works with this OS?

limit approaching infinity: (arcsin(x))/(x)

= 0

Question is: Why? The 'Sandwich Theorem' 0=[(arcsinx)/x]=0 gives this
solution, but looking at the graph of (arcsinx)/x , this appears
impossible.

lim x->OO [arcsin(x)] - {DNE)
lim x->OO [(arcsinx)/x] - {DNE/OO}

lim x->OO [-Pi/2x] = lim x->OO [(arcsinx)/x] = lim x->OO [Pi/2x]
=> 0 = [(arcsinx)/x] = 0

=> lim x->OO [(arcsinx)/x] = 0

HOWEVER: (-Pi/2)<[arcsinx]<(Pi/2) ... SO ... 

Greetings all

I would like to show the x y values next to the point on the plot does maple have a command to do this?

data := [[0, 0], [.5, -1], [1, 0], [2, 2], [3, 0], [5, -4], [7, 0], [11, 8], [15, 0], [18.5, -7], [22, 0], [24.5, 5], [27, 0]];
 with(CurveFitting);
cubfit := BSplineCurve(data, x, order = 3);
plots[display](plot(data, style = point, color = black, symbol = BOX),
plot(cubfit, x = 0 .. 27, thickness = 2))

What is the best way to print a maple file?  It seems that a lot of white space is added when making an html file.  Also it scrambles in a ton of strange symbols when its in a pdf, Im just trying to figure out how to print a 3 or 4 page maple worksheet without it printing on 20 pages!

 

Thanks!

How can I plot sin(y)>0, x>0 ?

I've tried using inequal:
with(plots):
inequal({sin(y)>0,x>0}, x=-2*pi..2pi, y=-2*pi..2*pi);

but I get the message 'unable to compute coeff' .

Thanks in advance.

I'm interested in finding a command that could stretch slope fields for me. Or perhaps I need to make a procedure of my own?

If that is the case, I would like to know how to draw a segment of a graph by varying the slope.

I think it is possible for me to use

with(geometry);

segment([y=y'*x+C, [x,y]],a,b);

But I don't have any idea how to make a program out of it yet.

 

Thanks in advance :)

Can I have maple show me the steps it takes to integrate?  Is this possible?

 

thanks!

Hi, I can't find any information what does FI mean, for example: f := proc(x) if x>0 then x else -x fi; end proc: f(-3); or: if iseuler(G) then continue else RETURN (print ("The graph does not have an Euler circuit")) fi; I'm tired of googling already, Maple Help doesn't have any information about fi, what might it be? perhaps some closing declaration instead of 'end if'? I would be grateful for any comments, thanks in advance, Sven

is there any way of creating a polynomial in maple from a list of coefficients (i could write my own function, but this is annoying, no?). specifically i would want an inverse to the PolynomialTools:-CoefficientList function, f([1, 2, 3]) would yield me 1 + 2*x + 3*x^2. i cant understand the apparent lack of such an elementary function, i must be missing someting? thanks

Hiya,

I have two questions...
Firstly when plotting a graph in Maple using plots[display]({A1,A2,A3}), is there anyway to switch the horizontal and vertical axes such that f(z) is on the horizontal axis and z along the vertical?

Secondly, I'm trying to plot a sum at various times t,

c(z,t):= Sum(A[n]*Phi[n](z)*exp(-lambda[n]*t), n = 1 .. 10)

I several peaks from emission spectra which I am trying to fit wit a Gaussian distribution. 

y = y_0 + A*exp[-{(x-x_0)/(width)}^2

 

The problem I am running into is I am getting fits which are wrong.  Maple returns:

fit_658 := 1.+1.*exp(.50000000000000*(z-1.)^2)

The correct answer is:

-7e05+2.7e06*exp(((z-656.1)/9)^2)

Also, I am interested in finding the deviation in the parameters which are found.

I know how to solve a problem in Maple, but can't translate into Maple TA. I'm teaching elementary statistics, and want students to estimate a median using a cumulative frequency distribution.

In Maple, I randomly generate some intervals and frequencies. Then I define the CFD by giving the end points and the cumulative frequency, like;
(1) XY:= Array([[x0,cf0],[x1,cf1],[x2,cf2],[x3,cf3],[x4,cf4]]);

I would like to do something like a derivative with respect to a vector or really anything involving a vector (not of a known length or known values) going in and a vector coming out:

 

diff( Transpose(x) * A * x, x)

Is this possible?

 

It's just that it is very different if you do x*(x+1) if x is a vector or if x is a scalar.  Does this make sense?
 

Any tips would be great!

Thanks,

Dave
