These are the steps that I need to do

determine the domain and range of the functioon

determine the intercepts and asymptotes of the graph

locate the x-values where f'(x) and f''(x) are zero or undefined

then i need to determine where the relative extrema and the points of inflection occur (this i should be able to do if I can get the graph)

i have to know how to do this for two kind of function for a test tomorrow I missed all week because i was sick and we are allowed to use the software on the test.

here are the functions

I am sure this is easy but I am so new to the software I just can't figure it out

I want to analyze the graph of f(x)=x^3+3^2-9x+5

I just can't seem to figure it out at all

i also need to do the same with the following function

f(x)=(x^2-2x+4)/(x-2)

Please please help i have a test tomorrow and can use the software on the test so i need to know how to do this

Hello,

I have a system which is below:

X6-n4-n2, -n3+n1, -n4*X17t+n2*X9t, n3*X17t^2-n4*X17tt-n1*X9t^2+n2*X9tt, 130*X9tt-60*X17tt*n2*n4+60*X17tt*n1*n3-40*n2*X11+981*n2+60*n2*n3*X17t^2+60*n1*n4*X17t^2, -1500*X9tt*n2*n4+1500*X9tt*n1*n3+2250*X17tt+1000*n4*X11-14715*n4+1500*n4*X9t^2*n1+1500*n3*X9t^2*n2, n1^2+n2^2-1, n3^2+n4^2-1

I need to do primedecomposition for it. Maple could not do this for me kernel was lost. However system is not very big.

I have a procedure:

duplicates := proc(L)
local newL,vals,T;
newL:=[x->x];
vals := {[1/2,1/4,3/4]};
for T in L do
if not (T([1/2,1/4,3/4]) in vals) then
vals := vals union { T([1/2,1/4,3/4]) };
newL := [newL[],T]
end if
end do;
return newL
end proc:

I want to take a wav file and plot a smooth curve across the top indicating the relative maximums then put those points in an array or matrix with their relative x values.

with(AudioTools):
aud:=Read("c:/Documents and Settings/My Music/sample.wav")
aud2:=ToMono(aud)

There are quite a few spikes around the maximums which would indicate multiple maximums at each max area but I just want the general max.

Dear Maple users

This may be a very simple question: How do I operate on the coordinates of a vector in the most streamlined way?

Lets say I have a vector <2,4,5,8,9> containing the diameters of five different circles. I want a vector V in which the coordinates are the corresponding circle areas. So the first coordinate of V should be 1/4*Pi*2^2, the next coordinate 1/4*Pi*4^2 , etc...  How is this done in the most simple way i Maple? In principle I want a method, which will work for any function ...

bonjour

je voudrais savoir s'il vous plait comment je peux mettre des commentaire sur mon graphe

exemple

 with(plots):m:=plots[complexplot]([1.2515620286261080311-5.7201210809568767578*10^(-17)*I, 6.7072785187480944199+5.0971180860199056453*I, 3.1902191682026148265+8.0995173273080639243*I],style=point,symbol=circle,color=red,scaling=constrained):m2:=plots[complexplot]([1-I,1.+I,3.-3.*I,3+3*I,-1.-2.*I,-1+2*I],style=point,symbol=soliddiamond,color=blue,scaling=constrained):
 

a:=%%, %;
 

what does this do?

Something simple

How do I convert an exprseq to a list

L:=seq(i,i=1..50)

L:=[L]   is this the only way to convert the exprseq to a list?  I thnk it's the simplest way, however is there another way?  The convert command won't allow it.

I have something like this:

months := Vector([1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]);
values:= Vector([45, 48, 53, 46, 41, 38, 35, 44, 50, 53, 55, 59]);
knots := ScatterPlot(months, values, style = point, symbol = asterisk, color = blue);
R:= LeastSquares(months, values, x);
curve1 := plot(R, x = 0 .. 12, y = 0 .. 70);
plots[display](knots, curve1);

R becomes

(459 / 11)  +  (243 / 286) * x
 

Hi all,

The following is my 'poor' attempt at coding the n by n queen problem. I am an amature programmer. The codes individually seem to work fine but when i put it all together it dose not seem to work and it does not produce an error so i don't know where its going wrong.

I would really really appriciate greatly if someone can help me please.

thank you in advance.
 

Hi
 

i am trying to code a proc that tells me when a certain function is better than another. My proc works fine for functions that have a single crossing point but it does not seem to work for inputs that have multiple crossing points.
 

Hi,

I'm a bit of a rookie with maple and need your help please.

I am looking to input a function of the following form:

f(x)= 1/2.x.H.x + g.x

where H is a matrix and g is a vector.

I need maple to be able to evaluate the function value at certain points.

Thank you in advance for any help you provide.
