As you can see this app performs the trace of a given path r (t), then locate the position vector in a specific time. It also graphs the velocity vector, acceleration, Tangential and Normal unit vectors, along with the Binormal. Very good app developed entirely in Maple for our engineering students.

It appears google doesn't know about the haversine formula.  Huh?  Well at least google can't draw the proper path for it.  I typed in google "distance from Pyongyang to NewYork city"  and got 10,916km.  Ok that's fine but then it drew a map

The map path definitely did not look right.  Pulled out my globe traced a rough path of the one google showed and I got 13 inches (where 1 inch=660miles) -> 8580 miles = 13808 km .. clearly looks like google goofed. 

So we need Maple to show us the proper path.
 

with(DataSets):
with(Builtin):
m := WorldMap();
AddPath(m, [-74.0059, 40.7128], [125.7625, 39.0392]):
Display(m):

Ok so you say that really doesn't look like the shortest path.  Well, lets visualize that on the globe projection

Display(m, projection = Globe, orientation = [-180, 0, 0])

Ah, now it is clear

As a momentary diversion, I threw together a package that downloads map images into Maple using the Google Static Maps API.

If you have Maple 2017, you can install the package using the MapleCloud Package Manager or by executing PackageTools:-Install("5769608062566400").

This worksheet has several examples, but I thought I'd share a few below .

Here's the Maplesoft office

 

Let's view a roadmap of Waterloo, Ontario.

 

The package features over 80 styles for roadmaps. These are examples of two styles (the second is inspired by the art of Piet Mondrian and the De Stijl movement)

 

You can also find the longitude and latitude of a location (courtesy of Google's Geocoding API). Maple returns a nested list if it finds multiple locations.

 

The geocoding feature can also be used to add points to Maple 2017's built-in world maps.

 

Let me know what you think!

This app is used to study the behavior of water in its different properties besides air. Also included is the study of the fluids in the state of rest ie the pressure generated on a flat surface. Integral developed in Maple for the community of users in space to the civil engineers.

A few days ago I was browsing through some books in my collection, that by Gradshteyn and Ryzhik in particular. What fraction of the intregrals, series and products therein can Maple handle correctly?  Besides special functions these properties are valuable components of symbolic mathematical software.  If the answer to this question is not nearly everything in that printed compilation, this inclusion in Maple is a worthy objective.

We have just released the 3rd edition of the Mathematics Survival Kit – Maple Edition.

The Math Survival Kit helps students get unstuck when they are stuck. Sometimes students are prevented from solving a problem, not because they haven’t understood the new concept, but because they forget how to do one of the steps, like completely the square, or dealing with log properties.  That’s where this interactive e- book comes in. It gives students the opportunity to review exactly the concept or technique they are stuck on, work through an example, practice as much (or as little) as they want using randomly generated, automatically graded questions on that exact topic, and then continue with their homework.

This book covers over 150 topics known to cause students grief, from dividing fractions to integration by parts. This 3rd edition contains 31 additional topics, deepening the coverage of mathematical topics at every level, from pre-high school to university.

See the Mathematics Survival Kit for more information about this updated e-book, including the complete list of topics.

Do you have Maple content that you want to protect from editing and viewing, while still allowing others to execute the code within and obtain results? In Maple, worksheets can be password protected so the users of your Maple application can benefit from the specialized routines you've created while the details remain hidden.


The password protection feature can be useful for a variety of situations, such as:

  • • Providing a Maple-based solution while protecting the intellectual property embodied in your algorithms
  • • Ensuring the users of your application can not accidentally make changes that break your code

 

To learn more about this feature in Maple, you can download the free Tips & Techniques from the Application Center.

We just posted a submission to the Maple Application Center that I thought people might be interested in. Mathematics for Chemistry isn't a typical application - it's an e-book, written in Maple by J.F. Ogilvie. It covers both standard mathematics topics chemistry students are expected to know,  such as calculus and linear algebra, as well as chemistry-specific topics like chemical equilbrium, quantum chemistry, and nuclear-magnetic-resonance spectra.

There's lots of interesting content on the Application Center, and the range of topics is always fascinating, but it's not every day I see an entire e-book come across my desk(top)!

If you are interested, you can find it on the Application Center, here: Mathematics for Chemistry

   It’s that time of year again for the University of Waterloo’s Submarine Racing Team – international competitions for their WatSub are set to soon begin. With a new submarine design in place, they’re getting ready to suit up, dive in, and race against university teams from around the world.

 

   The WatSub team has come a long way from its roots in a 2014 engineering project. Growing to over 100 members, students have designed and redesigned their submarine in efforts to shave time off their race numbers while maintaining the required safety and performance standards. Their submarine – “Bolt,” as it’s named – was officially unveiled for the 2017 season on Thursday, June 1st.

 

 

   As the WatSub team says, "Everything is simple, until you go underwater."

 

 

    Designing a working submarine is no easy task, and that’s before you even think about all the details involved. Bolt needs to accommodate a pilot, be transported around the world, and cut through the water with speed, to name a few of the requirements if the WatSub team is to be a serious competitor.

 

    To help squeeze even more performance out of their design, the team has been using Maple to fine tune and optimize some of their most important structural components. At Maplesoft, we’ve been excited to maintain our sponsorship of the WatSub team as they continue to find new ways to push Bolt’s performance even further.

 

 

   The 2017 design unveiling on June 1st. After adding decals and final touches, Bolt will soon be ready to race.

 

   This year, the WatSub team has given their sub a whole new design, machining new body parts, optimizing the weight distribution of their gearbox, and installing a redesigned propeller system. Using Maple, they could go deep into design trade-offs early, and come away knowing the optimal gearbox design for their submarine.

 

   In just over a month, the WatSub team will take Bolt across the pond and compete in the European International Submarine Races (eISR). Many teams competing have been in existence for well over a decade, but the leaps and strides taken by the WatSub team have made them a serious competitor for this year.

  Best of luck to the WatSub team and their submarine, Bolt – we’re all rooting for you!

We have just released an update to Maple.  It includes updates to the Maple Workbook, the video component, the Physics package, and many other small improvements throughout the product. It is available through Tools>Check for Updates in Maple, and is also available from our website on the Maple 2016.2 download page.

Ian Thompson has written a new book, Understanding Maple.

I've been browsing through the book and am quite pleased with what I've read so far. As a small format paperback of just over 200 pages it packs in a considerable amount of useful information aimed at the new Maple user. It says, "At the time of writing the current version is Maple 2016."

The general scope and approach of the book is explained in its introduction, which can currently be previewed from the book's page on amazon.com. (Click on the image of the book's cover, to "Look inside", and then select "First Pages" in the "Book sections" tab in the left-panel.)

While not intended as a substitute for the Maple manuals (which, together, are naturally larger and more comprehensive) the book describes some of the big landscape of Maple, which I expect to help the new user. But it also explains how Maple is working at a lower level. Here are two phrases that stuck out: "This book takes a command driven, or programmatic, approach to Maple, with the focus on the language rather than the interface", followed closely by, "...the simple building blocks that make up the Maple language can be assembled to solve complex problems in an efficient way."

 

 

 

A number of MaplePrimers have asked how one might use the section and subsections of a Maple worksheet to structure the source code of an extended Maple package.  The usual answer is that it cannot be done; a module-based Maple package must be assigned in a single input region in a worksheet.  A recommended alternative is to write the source in text files and use either command line tools or the Maple read command from a worksheet to assign the package.  Because the read command handles Maple preprocessor macros, specifically the $include macro, the source can be conveniently split into smaller files.

I prefer this file-based method for development because text files are generally more robust than Maple worksheets, can be edited with the user's preferred editor, can be put under version control, and can be searched and modified by standard Unix-based tools.  However, not everyone is familiar with this method of development.  With that in mind, I wrote a small Maple package, CodeBuilder, that permits splitting the source of a Maple package (or any Maple code) into separate code edit regions in a standard Maple worksheet, using $include macros to include the source of other regions.  To build the package, the code edit regions are written to external files, using the names of the regions as the local file name relative to a temporary directory.

The package includes a method to run mint on the source code.  The result can be either printed in the worksheet or displayed in a pop-up maplet that allows selecting the infolevel and the region to check.

CodeBuilder includes help pages and a simple example (referenced from the top-level help page) demonstrating the usage.  To install the package, unzip the attached zip file and follow the directions in the README file.

CodeBuilder-1-0-3.zip

Errata Just noticed that a last minute change broke some of the code.  Do not bother with the 1-0-1 version; I'll upload a new version shortly.  The latest version (1-0-3) is now available.

Just a simple graphical view of Maple releases over the years.

Can anybody please tell, where I can find seminar/workshops on Maple training ?
