## How to get the range of a function given it's doma...

Hi there,

I was woundering if there is a function implemented in Maple11, where I can enter a function and it's domain, and the output is the range. For example:

Entering f(x)=x^2, and the Domain x in (-1,2), I would want Maple to tell me that f(x) is in [0,4).

Is there such a function implemented? I need this quite often, most times on functions from R->R, but also more general for functions from R^n -> R^m. I know that in some cases you could...

## Assign linestyle in LineChart plot...

Hello,

I have the following problem:

I have an array of values stored in F[i,j] and plot them using the LineChart tool:

LineChart([seq([seq(F[i, j], j = dmin .. dmax)], i = 1 .. 3)], xcoords = [seq(0.1e-1*2^(k-1), k = dmin .. dmax)],  color = mycolor);

This way, I obtain 3 curves, each of them with a different color as defined by mycolor.

However, for a publication in black and white I would now like to assign different linestyles...

## Version Compatibility Maple 11 & Maple 12 - Ritz M...

Hello,

I am trying to use a worksheet developed by Professor Batista [ritz06.mws] for calculating plate vibration frequencies using the Ritz method, which is available from the Applications directory - Mechanical Engineering folder.  The worksheet was developed using Maple 12 and I am using Maple 11; a careful reading of the file didn't show any commands that were incompatible across the two versions and yet I am not able to solve the worksheet using the default inputs provided in the worksheet.  I have attached a PDF output of the file with the error message.  Any assistance that could be offered would be greatly appreciated.

Kind regards,

When I run the following Maple codes, for some reason I get an error:

> odePlot := DEplot(ode, P(t), t = -3 .. 3, P = 0 .. 1000);

Error, (in DEtools/DEplot/CheckDE) derivatives must be given explicitly

## How can i sum an expression numerically...

`Dears. I want to evaluate the following expression numerically`
`G[i]=sum(Gama[i,k], k=1..100, k<>i),`
`where`
`Gama=((x[k]-x[i])*xdot[k]+(y[k]-y[i])*ydot[k])*dtheta[i]/((x[k]-x[i])^2+(y[k]-y[i])^2)^2`

Dear all, I am using fsolve to solve a complex equation. When I solve it, I get the following error:

Error number of equations, 1, does not match number of variables, 2.

But the variables are just one (named u1) I think it is a problem with assume but I am getting cracy to understand the problem.You can find in attachment the short maple file. I try to solve equation e4 for variable u1.

thanks
Alberto
