I am trying to use Maple17 to create practice integration problems in which the integrands contain square roots.  I want the students to practice converting square roots, perhaps with fractions, to fractional and/or negative powers.  Hopefully Maple can typeset the integrals if I use the inert form "Int", and also do the integrals for me so I can find the answers quicker than doing it by hand, and not have to worry about making a careless mistake.  The trouble is, Maple is converting the square roots to fractional exponents:

I hope at least one of these works.  To make a long story short, when I display an integral using "Int", how do I prevent Maple from converting square roots to fractional exponents?





I have a matrix A4  

I have reason to believe that the expression below is a real number: 


A numerical approximation supports that. How can Maple help here to get a simplified expression?

t0 := arccosh(lambda/(s*(1-lambda)))

f := int(sqrt(lambda-s*cosh(t)/(1+s*cosh(t))), t = -t0 .. t0)

s := 1/10


g := f-Pi*(0+1/2)

Roots(g, lambda = 0 .. 1, numeric)

Why does maple say:

Error, (in mod/Expand) too many levels of recursion?

Dear All,

evalf(RoofOf(Z^6-3*Z^4+3*Z^2+Z-1,index=real[2]) fails to deliver a numerical value.

  1. I can use fsolve to compute the real roots but I need to replace all the occurences of RootOf by its numerical value in lengthy expressions.
  2. Also simplify(RoofOf(Z^6-3*Z^4+3*Z^2+Z-1,index=real[2],RootOf) does not work.
  3. I read the other posts related but could not find any answer.

Thanks for any help,



 I want to calculate successive roots of the following complex eq.

how can I set interval (?) for fsolve in the following code:

I'm solving a system of ordinary differential equations numerically, I used the dsolve(system,numeric) to do it. I have also plotted the solutions. Now I want to know where does this solution cross zero and use this value for later computations, is there a way to do it? 

This question is, as I think, equivalent to how to find the roots for a curve expressed in numerical arrays.

Thank you!

I have a solution with RootOF(_Z^6+....). I do not need to find the roots explicitly(I know that I should use 'allvalues' to find the roots). My question is "Is it okay if I use RootOF(...) expression in another equation without finding the roots explicitly? I mean does RootOF(_Z^6+...) stand for all its roots and can it be used for each roots?"

Thank you in advance.

Good day, dear Friends!

I'm trying to find real positive roots  of equation 

sqrt(x+3-4*sqrt(x-1))+sqrt(x+8-6*sqrt(x-1)) = 1 with Maple 16.01.

One can easly verifies that this euqation has at least two positive  real (integer) solutions: at x=5 and x=10,

but Maple function 

I am using the function solve() to find roots of a trig. equation. Such as for sin(k*x) = 0, Maple retuns x = 0, whereas I expecting to get  x = n ∏/k, for n = 0,1,2,.... I am sorry I am new to Maple, can anyone help me get what I am looking for?

Thank you

I want to solve two equations with all roots.


I am trying to solve a transcendetal equation that has no analytical solution (AFAIK).
My question is how to find different branches of solutions with Maple. So far, Maple
only returns one particular solution.

To fix ideas, my equation is of the type,
x-a*(1-x)* exp(bx)+c=0
For suitable values of a and b this equation seems to have, at least, two solutions in
the real axis and I would expect it to have a numerable infinite of solutions in the

Hey maple gurus

when i solve and equation with two real roots (1 positive and 1 negative roots), how do i automatically pick out the postive solution?

As you can see from the attached file, i used sort command to order it, and it works for examples1 and 2, but not for 3.

i guess i could use Abs cmd.....

I want solve this inequations

> solve((1/4*(beta^2-6))*(-beta^2+2*alpha) > 0);
After running, maple gives an answer in four lines alpha < (1/2)*beta^2 0 < -(1/2)*beta^2+3 (1/2)*beta^2 < alpha -(1/2)*beta^2 < -3 [] beta = -sqrt(6) [] beta = sqrt(6) now I have questions: 1) In spite of knowing range of beta in thhe second parts of first two lines of answer, why maple...

Find the principal arguments of the 5 roots of the polynomial:p(z)=z^5-5*z^4-5*z-5,and enter a decimal approximation to the largest principal argument in the box below.  Your approximation should be correct to 10 significant figures
