Hi all,

I'm getting started with maple. Want to solve the following integral:

int(     (  1+(a*x)^t  )^(-1/t)      , x = 0 .. z)

Constraint: 0<t<1

Maple 8 installed on an old WinXP gave me a solution with

hypergeometric functions. Maple 17 installed on a Linux64

gave me no answer at all. What could explain this difference?

Thx...

Dear all,

I would like to solve the following function:

f:=sum(Y[i]*ln(t[i]), i = 1 .. n)+(sum(Y[i]*t[i]^beta[1], i = 1 .. n))*ln(theta[1])/theta[1]^beta[1]-(sum(Y[i]*t[i]^beta[1]*ln(t[i]), i = 1 .. n))/theta[1]^beta[1]+(sum(Y[i], i = 1 .. n))/beta[1]-ln(theta[1])*(sum(Y[i], i = 1 .. n));

Hi 

Is it possible to disable/out comment lines in a maple sheet in a similar way to ctrl + r in Matlab?

Thanks in advance

Hi!

I'mtrying to use Maple's statistic and linear algebra packages to get a functionality similar R. The biggest problem that I have currently is to find an easy/simple way to import and access data from tables/spreadheets in ascii notation (essentially what read.table(<filename>, <options>) gives you in R). I tried to use something like M:=ImportMatrix(<filename>) for that, which actually reads a table, but I don't know how to use to access/use the...

Hi,

New to maple and I have 2 questions that I'm stuck on.

1) Find the principal arguments of the 5 roots of the polynomial

and enter a decimal approximation to the largest principal argument in the box below.

ans: 2.589502038

2) Find the moduli of the 5 roots of the polynomial

and enter a decimal approximation to the largest modulus in the box below

ans: 2.34880159160143

I dont really know what to write in maple to get the answer. So, if someone could help me out that would be really great. cheers

Hello,

I'm trying to sort a list of symbols respecting some assumptions I have made about them. For example, I'd like to assume that 0<x<1, and I would like [x, x^2, x^3] to be sorted into [x^3, x^2, x]. How would I accomplish that? Making an assumption with assume() does not affect anything, as the sort() function does not seem to be actually comparing the values of symbols (only numeric values). Any help will be appreciated.

Thank you. 

Dear All,

I need your help, what function in Maple must be used to find the different form of this function

into this function

Diff(x1(t),t) - x2(t) = 0;

Diff(x2(t),t) - x3(t) = 0;

Diff(x3(t),t) +3*x3(t) + 4*x2(t) + x1(t) = 2*Diff(u(t),t$2) + 5*Diff(u(t),t) + 7*u(t);

multiply above system by test functions -lambda1(t),-lambda2(t),-lambda3(t) and integrate by part

in order to find adjoint operator in the form

x1 -> Diff(lambda1(t),t) - lambda3(t) = miu1(t)

x2 -> Diff(lambda2(t),t) + lambda1(t) - 4*lambda3(t) = miu2(t)

This is what i have done to find the difference between a ball thrown with different starting angle, and then ploted they into the same plot.

Hi,

I am a new maple user and I am having a problem with this question:

 .

here is my maple procedure. I have to make the iteration works until I have met the initial condition it will stop. the initial conditions here is z:=ic.

This is my approach:

sum(1/(4*n+1/3*k),k=1..infinity)

but I end up getting infinity for my answer which is obviously wrong.

I am using Maple 13, I am working on Optimtimization package (worksheet mode) in command-line 

I am a student taking differential equations and I need to implement Euler's method using Maple 17. I have set up a do loop that looks like this:

for i from 1 to n1 do

k:= f(t,v):

v:= v + h*k:

t := t + h:

od:

Where n1 is initialized to 50, f(t,v) := 0.0207v² -893.58, and h is 0.1. v and t are both initialized as 0.

Hi ,,,,  I think it is a bug in Maple   "try to calculate int(abs(x-2),x);   ... does not give a right answer
