i need to plot points on 2D from text file saved on c directory

please help me

Hello, so i have been given the daunting task of figuring out what some maple stuff means in a worksheet. Now this is complete gibberish to me so i was hoping someone can kind of dumb it down for me and explain what is going on in the BOLD TYPE portion of the worksheet below. At the bottom i have also attached my maple file so you can look at it in actually maple. What the professor has asked from me is;

sum(((n+1)/n-1)*(12*n^2+12*n+1)/((1+((n+1)/n)^(1/3))*(12*n^3+18*n^2+6*n)), n = 1 .. infinity)

hello, im trying to numericaly solve this differencal equaion and i cant see what the issue is with my boundery condions. the only thing i can guess at is the bondrey conditions are ant the limits of the range im intergrating over. any help would be amazing

E := -2;

                                     -2

⊆

not this form “⫋”

Hi I 'm using algsubs and i want to substitute p=((m-b)/m) in the

expression

f:=((m-b)/m)^2m+b^2*m so that

i obtain

p^m+b^2*m;

When i use algsubs((m-b)/m)=p,f) it does simplify.

Then i use algsubs(m-b=m*p,f) i got p^m+(1-2*p+p^2)*m

i do not want the last part to be expressed in terms of p.

I will appreciate your help and suggestion.

Thanks

Hi!

I have a long formula having 6 variables in it of which 2 can be set 'freely', all others have assumed resctrictions to be real and positive. The formula in overall has to produce a real valued result. Is it possible with Maple to find out a formal expression for the 2 'free' parameters where all the assumptions will be met?

Thank you!

I want to disable automatic simplification for certain operation(s), for example, instead of usual response

How would i plot this surface? 7x+22xy+7y+14xz(sqrt(3))+14yz(sqrt(3))-5z=180

I havn't ever used this program before and my teacher didnt teach us how to use it and wants us to use it.  I tried to plot it but dont understand how to.

Hi there,

B:=Matrix(3,4,[ListTools:-LengthSplit([1,2,3,4,5,6],4)],fill=32);

C:=[seq(i,i=B^%T)];

What's the most efficient way to delete the 'extra' 32s when converting it back?

Thanks.

Hello everybody,

I am happy to join you.

Well... I have an inverted pendulum modelisation, with several theta, theta dot, double dot ...
With Lagrange method, I need to derivate by Theta1(t) dot. However I am unable to do it.

My question is: How to do diff( 5x^2+y,  x^2) ???

The result should be 5.
 

I have I will be able to adapt yours answers to my probelm succesfully.
Many thanks

Ps: I use Maple13.

I use maple sovle an optimality question with hamilton function, but the results are quite different from the given result using matlab. I do not know where I'm wrong ,so can anybody help me ?

Thank you very much!

I am trying to fit the solution from  one nonlinear ode and compare with a set of experimental data. How can I  do this ?.

Thanks in advance... and  any comment will be usefull.

Greetings All

I'm trying to find repeating numbers in the golden mean like 618, 619,645 etc..

I'm getting error message because of syntax and the decimal point how do I take the decimal point out so instead the string is 618 instead .618

How do I get rid of the decimal point in a string?

example

p:=evalf((1+sqrt(5))/2-1,20);

ns:=convert(p,string);

seq(Take(p,i),i=0..20)

SearchText(678,p)
