I used convert(problem,parfrac,x) and it gave me an error saying augment not a rational function.

(3x - 1) / x(x-1)

want to diplay it like this

A/X + b/(x-1) then coming up with the answer like this 1/x + 2/(x-1).

Newb to maple and this is my first post. Thanks

please help me here:

 

how can we find:

sum((5/2+2310*n^5+5775*n^4+5019*n^3+(3507/2)*n^2+(409/2)*n)/(27720*n^7+97020*n^6+132300*n^5+88200*n^4+29400*n^3+4410*n^2+210*n), n = 1 .. n-1)

 

Maple is giving answer which is very complex

please help me here:

we want to find:-

sum((5/2+25*n^2+25*n)/(300*n^4+600*n^3+360*n^2+60*n), n = 1 .. n-1)

maple gives me an answer which looks complex to me? can we simplify it further?

 

thanks

 

I'm trying to do this project but I keep getting an error message...does anyone have any ideas???

 

I find it much easier to enter equations in the Text mode (red bold text). In the past I found a UI setting that allowed me to stay in this mode, but now I can't remember where to find the option...so every time after I input a command, the next command is back in Math mode by default. How can I make it stay in Text entry mode all the time?

Hello, I have a function that produces different phase portraits as you change the variable x in the original equation. Im trying to find out at what values of x this change occurs...
 

So far I have determined the eigenvalues with regards to x and have run loops to find out roughly when this happens but i would like to be able to do this with either a procedure of perhaps dsolve or solve maybe?

 

So, given the eigenvalues, how would i go about doing this?

For a matrix W, the command limit(W^t,t=infinity) does not work.  Is there a way to evaluate this limit in maple ??

I knew that fsolve can solve equations by given an interval or a starting point. Like these

fsolve({x-y = 1, x+y = 1}, {x = 0 .. 1, y = 0 .. 1})

fsolve({x-y = 1, x+y = 1}, {x = 0, y = 1})

But what if I knew the interval for only one of the the variable?  After I run this code

S={v1=[-4 v2=[7 v3=[-3 v4=[-6 v5=[1 }
           -2       1        3        -6       3
           -1      -2        0        -1       4

Is there a way to check a function for positive definiteness or local
positive definiteness?

Eg:  v(x1, x2, t) = (x1^2 + x2^2)*exp(-t)

please help me here:

we have the following series:

1/2-Pi/(4*sqrt(3)) = sum(1/((6*n)^2-1), n = 1 .. Infinity)

 

(5-Pi)*(1/4) = sum((-1)^(n+1)/(2*n+1), n = 1 .. Infinity) {***}

 

-1/5+(1/6)*Pi-(1/12)*sqrt(3)*log((2+sqrt(3))/(2-sqrt(3))) = sum((-1)^n/(6*n+5), n = 1 .. Infinity)

 

  Dears,  I'm using Maple 11.   In math mode, I want to input  a notation with a line or tilde above it. But I don't know how to do it. And I need some help.

please help me here:

i have :

h(x):=arctan(tan(x)*tan(x)):

how do i find:

int(h(x),x=0..Pi)

i think its value is pi^2/4

suppose if we also have

g(x):=arctan(cos(2 *x))+Pi/(4):

how do we find:

int(g(x)-h(x), x = 0 .. Pi)

thanks

 

Hello,

I have got the following problem:

my data is stored in 3-dimensional arrays but I need my data as Vectors in order to call the function FourierTransform.

Right now I transform it by hand like this (my data is stored in the 3-dimensional array fArray):

fVector11:=Vector(N):
fVector12:=Vector(N):
fVector21:=Vector(N):
fVector22:=Vector(N):

I'm using Bodeplot comando:

Bodeplot(sys,decibels=false,subsystem=[[1,1],[1,4],[1,5]]);

This gives three grafs in the plot.

Do anybody know how I can get Maple to add up the grafs into one graf?
