Convolution of Finite Discrete Signals Tutorial Convolution of two finite discrete signals is a topic discussed in the Signals and Systems course offered by any electrical engineering faculty. This tutorial was created using Maple 10 using Maple components and can be use as part of computer aided teaching material or as a guided interactive tutorial. This worksheet can also be deployed on the web by using MapleNet. [

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.
sketch the following and convert to rectangular:
> 1.)x=t^(3), y=t^(2);
2.)x = (sec t)+2, y = (tan t)-1
3.) r = 2+2sin4thetha
4.) r = 4cos2theta
find the dy/dx of the following:
> 1.)x=t^(3), y=t^(2);
2.)x = (sec t)+2, y = (tan t)-1
3.) r = 2+2sin4thetha
4.) r = 4cos2theta
find the equation of the tangent line to the function with the indicated information:

In this episode Tom Lee sits down with John McPhee the inventor of Dynaflex Pro, in his office at the University of Waterloo to discuss dynamic models of physical systems, difficulties one might encounter when commercializing a product, and his work on modeling the piano hammer action. Paul Goossens joins us via telephone from the American Control Conference to talk about

DynaFlexPro and other engineering products; and we bring you an interesting selection of news and mailbag items.

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.

for engineering purposes the ability to input a multi-variable equation in one form and then apply the known variables and solve for the numeric unknown is very handy. such as an equation of horesepower,torque and rpm. is there an easy way to do this in maple 10?

Jim Herod has a wonderful set of lecture notes—accompanied by a collection of Maple worksheets—which introduce linear operators on infinite-dimensional Hilbert spaces to beginning graduate students in science and engineering. Entitled

*Linear Algebra, Infinite Dimensions, and Maple*, these notes were developed from a one quarter course which Prof. Herod taught many times at the

Georgia Institute of Technology. The notes are very concise and have been refined and improved many times over the years in response to student feedback.

I'm working on some basic complex number equalities in engineering class, and was practicing converting from cartesian to polar coordinates. Maple can help by telling me if my conversions are correct by telling me whether the equality is true. For example, for the complex number: 5 + 3*I maple will verify the following:
is(5+3*I = polar(sqrt(5^2+3^2), arctan(3/5)))
true
it will also verify:
is(polar(sqrt(5^2+3^2), arctan(3/5)) = sqrt(5^2+3^2)*exp(I*arctan(3/5)))
true
lastly, it will of course verify transitively:
is(5+3*I = sqrt(5^2+3^2)*exp(I*arctan(3/5)))
true

Maplesoft should have free recorded webinars available for customers, as The Mathworks does. The main problem people have with Maplesoft products is the lack of training. With recorded webinars you can get a general idea of how to use Maple to solve your engineering problems.

Gilberto Urroz, Utah State University is a prolific Maple user. His Web site contains a wide range of useful resources that he's developed. Of particular interest might be his material in various topics in Civil and Mechanical engineering.

Maplesoft offers a series of Web seminars on various topics relating to its products (see

Current list of Web seminars ). They range from specialized technical topics to more promotion-oriented product demonstrations. There's a couple coming up shortly that I wanted to draw your attention to:
