Is there a command the takes (A*B)^a and returns A^a*B^a ?

I tried expand and  simplify and also used assuming a>1 but without luck here...

I know this is very basic but I have monster product expressions that I need to be able to raise every term inside the parenthesis by the power so I can isolate some terms of interest.

In MapleSim, it is possible to constrain a rigid body in a multibody system to an arbitrary constraint? 

Similarly to how a mass at the end of a simple pendulum can only move along a circle defined by the length of the pendulum, I was hoping to constrain one to a shape like an ellipse or sine wave.  I could then give it initial velocities and see how it would move along the shape over time.

I'd like to be able to define this constraint with an equation. ...

Hello everybody !

Do you know any mean to find the number of iterations of the simplexe algorithm used in the Minimize pocedure?

Thank you very much for your help

How do you plot the following parametric equation (equation of an ellipse) in the same graph

Hi there,

Unfortunately I don't have access to Maple because I am away from my office for the week, but I need a

system of linear equations solved. Can someone please solve it for me and post the solutions (if any)?

The system is:

a_1 x_1 + b_1 x_2 + c_1 x_3 + d_1 x_4 = e_1 + e_4

a_2 x_1 + b_2 x_2 + c_2 x_3 + d_2 x_4 = e_2

a_3 x_1 + b_3 x_2 + c_3 x_3 + d_3 x_4 = 0

a_4 x_1 + b_4 x_2 + c_4 x_3 + d_4 x_4 = e_1 + e_4

I am supposed to adjust the code my teacher gave us for a project. The only problem is I dont know anything about maple or much about what I am supposed to do. I tried copying and pasting the code but I couldn't.

The assignment says to adjust the code to incorporate variable window size. There is a place in the code where it says insert code here and the teacher said it shouldn't need more than like 8 lines of code.

If anybody thinks they they can help I will be more then happy to forward you the email.

I need the list of x and y separately of S[2] like the:

[.8098169753, 0.8098169753, .8098169753, .8098169753, .8098169753, .8098169753]

[1.339721710, 1.309892054, 1.282898312, 1.258277638, 1.235670705, 1.214793049]

restart; with(LinearAlgebra);
a := 2; b := .29; d := 1.85; for h from .5 by .1 to 1 do
eq1 := x*(-b*x^2-x+1);
eq2 := y*((a*x*x)/(b*y^2)-d-h*y);
S := solve({eq1, eq2}, {x, y});

working on my exam notes for tomorrow, I get this...

and only 1/3 or so of my document opens... anyone that can help me out here..?  

I use Maple 17... 

I want to choose four points A, B, C, D on the sphere  (x-2)^2 + (y-4)^2 +(z-6)^2 -81=0 from the list L so that there are not any the right triangle are formed from the points A, B, C, D. How to get it? I tried

I am also having trouble with limits when I have indexed
variables.   That is, how do I tell Maple to assume every element of
an indexed variable is positive?

Here, I show that normal limits work.

When I was programming on Python, the "up arrow" key could copy a previous command line that I have entered, but I'm not sure if such a shortcut exists in Maple.

For example:

INPUT: 2+2

OUTPUT: 4

Presses "up arrow key"

2+2

Thanks,

Say I want to find the derivative of x^2+2x-3 when x = 2

i.e. f'(2) where f(x) = x^2+2x-3

How would I do this?

Thanks.

how can i define a matrix as a sunction of a variable so that when i chande the independet variable,the elements of the matrix also change?

A(t):=[a[t],b[t],c[t]] ; i want to define a function like this,so that by changing the time t,the elements of the matrix also change,what should i do?

How does one take the gradient of a expression involving sums in terms of a set of indexed variables.

I am trying to find the maxima for the satisfaction for a public good from a tax code. The sum represents the total revenue. The tax code is defined as a piecewise linear function of income and indexed variables. The indexed variables represent the points of the kinks and the marginal tax rate for each income bracket. (The set of indexed variables will vary...
