can I change the behavior of maple to not represent 1/sqrt(2) as sqrt(2)/2? I guess in a mathmatician's view this is a simplification, but not from an engineering standpoint. also, if I perform combine(sqrt(2)/(sqrt(m)*sqrt(k)),radical,symbolic) I get sqrt(2)*sqrt(1/m k) instead of the desired sqrt(2/(k*m))..is this related? I'm sure there is a nuance that I am not getting...

## Older Maple Finite Element Method Package...

Fedderik van der Bos created a worksheet for the Finite Element Method that is available in the download section for engineering applications; problem is, it uses a maple package (FEM) that is not posted on the site. The application is dated 2000. Does anyone have a copy of this package?

## Is there a way to find out the rate of decay of fu...

Is there a way to find out the rate of decay of function f(x) when x-> +infinity? Hi all, I just wanted to use this real-world engineering problem to practice problem-solving using Maple. Suppose I have a function f(x) (probably complex valued), how to find out its rate of decay as x approaches +infinity? I used "limit" but it will give me a value, not a functional form. I already knew my function has a limit =0 at x=+infinity. And it is of fast decay. I would like to bound the limiting behavior of f(x) by exp(-alpha*x) for some suitable constant alpha. Is there a way to handle this in Maple?

## Math code generation in C/C++? Can Maple or Matlab...

Hi all, I am asking this for my engineering friend. We've posted on Maple newsgroup and we just heard that here is another place where Maple experts appear, so we posted it again here to seek more advice -- because we have a struggling problem which annoyed us for several days already! Thank you! ---------------- Here is what I want to compute: t22 := Re((1/2*(a^2+2*sigma2*(c+g*(ee+i*v)))^(1/2)*exp(.5*a*t)/ (1/2*(a^2+2*sigma2*(c+g*(ee+i*v)))^(1/2)*cosh(1/2*(a^2+2*sigma2*(c +g*(ee+i*v)))^(1/2)*t)+.5*a*sinh(1/2*(a^2+2*sigma2*(c+g*(ee +i*v)))^(1/2)*t)))^(2*a*xbar/sigma2)) Assuming all variables are real and positive...

## Maths for Engineers

by:
Having looked recently at a suite of engineering software in use, I wondered whether engineers would need maths for much longer. Of course they’ll always need sufficient for business purposes, but my guess is maths will become unnecessary for engineering in much the same way as it’s unnecessary for weather forecasting. There would probably be a residual role for maths in engineering research, but not in the mainstream, and that would have huge implications for schools and universities. How do those engaged in teaching maths to budding engineers see the future?

## Help Me

Iam a Student in the faculty of engineering Petroleum department. Iam Studying Oil Reservoir Simulation which havs many models. Iam Studying the mathematical modeling of those reservoirs. In this modeling we use PDEs to model that reservoir behaviour for years we devide the reservoir into grid blocks each of its special dimensions and parameters so for each grid block there are 3 phases which are oil, water, and gas equation (one for each phase of them)(Matrix Dimension = No. of phases * No. of grid blocks) in addition to the other parameters there are some elements of the PDEs which is function in more than one parameter

This worksheet can also be deployed on the web by using MapleNet. [New Maple Applications]

## Reverse y-axis direction...

In structural engineering the y-axis direction in beam deflection calculations is reversed. A negetive deflection is an upward deflection. I need to plot the deflection. A simple reflect command will do part of the trick, but the tickmarks are not reflected. How do I reverse the y-axis direction so it will be negetive to positive from top to bottom? Thanks.
