1. Math tip - Earth Geometry<\/h2>\n
Several readers asked me for an article on 3-D earth geometry<\/b>. So I wrote a special new section in Interactive Mathematics on this interesting topic.<\/p>\n
It's a good article for those of you who are studying trigonometry<\/strong> or vectors<\/strong> because you can see how these topics are applied in the 'real world'.<\/p>\n Here's the link: 3-D Earth Geometry<\/a>.<\/p>\n The latest IntMath Poll asked readers how they feel when their math teacher asks them to go to the board to solve a problem in front of the whole class.<\/p>\n It seems that this is not a popular task (among readers of Interactive Mathematics). The results from 2000 voters:<\/p>\n 39% It's OK So a total of 61% reported that they don't really like solving problems in front of the whole class.<\/p>\n I asked this question because many students have reported that going to the board is an activity that increases their math anxiety<\/b>.<\/p>\n What are your thoughts on this topic? You can comment here<\/a>.<\/p>\n The current IntMath Poll<\/strong> asks you where your math anxiety comes from. You can vote on this topic in Interactive Mathematics<\/a>.<\/p>\n 1) Friday Math Movie - Sine Wave to Square Wave using Fourier Series<\/a> 2) Friday math movie - Bass guitar design<\/a>![\"Image:](\"\/blog\/wp-content\/images\/2008\/11\/asia.jpg\" "\\"asia\\"")

\n2. Latest IntMath Poll - Going to the board to do math<\/h2>\n
\n32% I hate it
\n29% I'm uncomfortable<\/p>\n
\n3. From the math blog<\/h2>\n
\nThis movie cleverly demonstrates what Fourier Series really gives us.<\/p>\n
\nHere's a video showing how math is used when making a bass guitar. It's part of a series from The Futures Channel.<\/p>\n
