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...

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?

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

Hello all!
How can I get Maple 10 to output it's numbers using engineering notation (milli, micro, Mega, Giga, etc) instead of indices?
Thanks

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.

thank you georgios kokovidis for acknowledging my question.thank you so much!however i still have questions.can anybody here please help me with this type of questions,im not an engineering or math major,so you can guys say im so bad with math.please help me.this are the questions.

Hi, all.
I want to write viewer/converter for mw/mws, so mw/mws format description needed. Google say nothing about mw/mws format. search.maplesoft.com likewise.
Can somebody help me with mw/mws format description? Is it possible to obtain such info from Maple developers? Is reverse engineering of mw/mws prohibited?

Maplesoft just announced that a new version of Maple has been released that works on Intel based Macs. You can get full information on how to download this update on the

Hello world! Please help!
I have two approximations for Fmax, one an implicit (for FmaxI) and one explicit (for FmaxE) , (with effectively the same one variable, md)and want to plot the percentage error between them? So far Ive been using implicitplot to plot FmaxI like so:
plots[implicitplot](eqFmaxI=0,md=0..500,FmaxI=0..1E-3);
all of the other plots ive tried dont seem to work
any help would be much appreciated, this is for my 3rd year engineering project. Thankyou, Mark.

Hello world!
Please help me;
How do i make my embedded button, autoexecute the whole worksheet? Or a section of code(does it need a string name)
This is for my 3rd yr engineering degree project, any help much appreciated!

Can anyone help me please?! Cash Reward!
My program solves my implicit equation but i am having trouble getting more than one result, ie, varying one of the variables. The best i can do is make a loop which gives a table of results which requires individually copying the results across into Excel for anysort of graph. Ideally i want to be able to plot the results in Maple, for any variable. This is for my 3rd year engineering project, any help much appreciated.
