At last! GeoGebra Applets in WordPress blogs!

GeoGebra, Software Tutorials

Micky Bullock of the Secret Garden of Maths has created an tutorial on how to embed GeoGebra applets in hosted WordPress blogs (as of yet, GeoGebra applets do not still work in WordPress.com blogs) . And the applet below shows that it really works (big smile).

I am planning to create a simpler tutorial about it next week, with Micky’s permission, of course.

Thank you Micky!

Introduction to the Geometer’s Sketchpad

Geometer's Sketchpad, Software Tutorials

This is the first part of the Geometer’s Sketchpad Essentials Series.  In this post, we will learnabout Geometer’s Sketchpad and its environment before we use the software.

Geometer’s Sketchpad (GSP) is a commercial geometry software created my Nicolas Jackiw in the 1980s. It is similar to GeoGebra, but with fewer tools. On the one hand, it is more difficult to construct geometric objects using GSP compared to other dynamic geometry software; but, on the other hand, it can be inferred that because of the lack of tools, it may improve geometric construction knowledge better than many geometry software.

The Geometer’s Sketchpad (version 4.07) window is shown in the figure below. For now, we will be using this version in our tutorials (I have not bought a new version yet).  However, all of the tutorials in this series are also compatible with the latest version (version 5). » Read more

Literature and Poetry, Math Lite

Most colleges here in the Philippines use the 1-5 grading system, 1.0  being the highest and 5.0 being the lowest. The passing mark is 3.0. Because it is relatively difficult to pass most courses (and exams) in our university compared to other other universities in our country, some students are quite  happy to get 3.0, especially in  difficult courses.

That probably inspired the writer of the poem below. That poem is printed at the back of t-shirts sold at the university.  One day, I heard three freshmen talking and laughing about wearing the shirt. One said, ‘I won’t wear that shirt ’til I graduate. My classmate wore it and he got a 3.0 in Math 17 (Algebra and Trigonometry). Believe me, those shirts are cursed,’ and they all laughed.

The poem is  a derivative the poem “Tree” by Joyce Kilmer. Honestly,  I do not know who is the author of the poem. Kindly tell me if you know.
