## Error between implicit and explicit approximations...

by:
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!

## Implicit equation plotting

by: Maple
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. > restart; > with(LinearAlgebra): > # IMPACT OF A FLUID FILLED SPHERICAL SHELL ("NON-HERTZIAN") WITH A "HERTZIAN" BALL-

## Can maple behave like tksolver or a hp48 calculato...

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's Lectures on Hilbert Spaces for Science...

by: Maple
MaplePrimes own 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.

## Bug with complex number equalities?...

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

## Webinars

by:
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.

## (News) New product: DynaflexPro for engineering...

by:
FYI: Maplesoft just released DynaflexPro , a new product that generates equations of motion for physical systems (including mechanical, mechatronic, and others). Automatic generation of model equations is one of the most powerful and popular applications of Maple in the engineering fields and Dynaflex offers a lot of tools to make this more efficient.

## I've got problems. Maple won't start. 9.5 or 10, b...

Hello everyone, my first post here. I'm studying mechatronic engineering at university so Maple is somewhat of a godsend. I got Maple 9.5 some years ago and it worked perfectly. But sometime last year it started going wrong. Whenever I tried to start standard maple it would give me some cryptic errors and refused to start. I had to resort to using Maple classic worksheet and it works just fine. Try as I might I could not discern the cause of my problems. I tried disabling my firewall and a number of other suggested fixes, none of which helped. Recently I was given Maple 10.0 and I thought installing it might fix my problems. I wasn't so lucky. I get essentially the exact same error when attempting to start Maple 10.0:

## Maple and Genetic Algorithm Optimization?

by:
Hi to all. My first post. I'm new to Mapleprimes, but have been involved with Maple for a few years. I would like to have a generalized genetic algorithm optimization tool that I could use to explore various engineering system optimization problems. I'm not aware of anything "out there" in this area. Is anyone aware of such a tool (open source or commercial)? Sherrell @ Oak Ridge National Lab

## (News) Maplesoft releases Advanced Engineering...

by:
FYI, Maplesoft has just released an e-book called Advanced Engineering Mathematics with Maple (R. Lopez author). Engineers among you will recognize the title as it is used by several popular texts. These books cover most of the primary mathematical topics encountered in engineering.

## Toronto, Ontario

by:
The University of Toronto is Canada's largest university and considered one of its very best. Its downtown campus (St. George) campus is the original site with all of the older buildings (circ. mid 19th century) and most of its most prestigeous faculties. Of note for the math crowd would be the Fields Institute .

## Report from NI Week (National Instruments)

by:
Last week, Maplesoft exhibited at NI Week in Austin, Texas, the primary conference for the National Instruments (NI) user community. They are best known for their data acquisition and testing hardware. More recently, through their software product LabVIEW, they have been becoming significant in the general modeling and simulation space.
