In this Newsletter:<\/p>\n

1. How to reflect a graph through the x-axis, y-axis or Origin?
\n 2. Visual.ly data visualization
\n 3. Resource: Thinkfinity
\n 4. Friday math movie: Time to re-design medical data
\n 5. Mow your lawn efficiently - use math!
\n 6. Puzzles
\n 7. Final thought: Greatness <\/p>\n

Please note: <\/strong>During the northern summer break (while most math students and educators are at the beach, summer camp, working or mowing lawns), the IntMath Newsletter is published once per month. <\/p>\n

1. How to reflect a graph through the x-axis, y-axis or Origin?<\/h2>\n

Suitable for:<\/strong> Everyone<\/p>\n\n\n\n
\"What<\/a><\/td>\n\n

A reader asks how to graph f(-x) and -f(x), and what does it mean?<\/p>\n

How to reflect a graph through the x-axis, y-axis or Origin?<\/a><\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

2. Visual.ly data visualization<\/h2>\n

Suitable for:<\/strong> Everyone<\/p>\n\n\n\n
\"visual.ly<\/a><\/td>\n\n

Visual.ly is a neat new data visualization tool. Worth a look, but it's still new. This could be a great tool for class projects in math. <\/p>\n

Visual.ly data visualization<\/a><\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

3. Resource: Thinkfinity<\/h2>\n

It appears this one has disappeared.<\/p>\n

\n

The resources I've been sharing in this space over the last several IntMath Newsletters was based on \"Ten great sites with free teacher resources\" from e-School News. <\/p>\n

4. Friday math movie: Time to re-design medical data<\/h2>\n

Suitable for:<\/strong> Everyone<\/p>\n\n\n\n
\"visual<\/a><\/td>\n\n

Here are 2 videos that talk about how personalized patient data in visual form has immense implications for human health.<\/p>\n

5. Mow your lawn efficiently - use math! <\/h2>\n

Suitable for:<\/strong> Everyone<\/p>\n\n\n\n
\"Optimize<\/td>\n\n

This is a fun article from Australia's The Age<\/em> newspaper. It describes how you can use geometry to optimize your effort. <\/p>\n

A Victa-ry for mathematics [no longer available]<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

6. Puzzles<\/h2>\n

Last mail I posed the question "Can you use five 5s to make 100?<\/span>".<\/p>\n

Here's one possible solution:<\/p>\n

(5 - 5\/5) × 5 × 5 = 100 <\/p>\n

Did you get any other answers?<\/p>\n

Here's a new one:<\/p>\n

\n

"My husband's age," remarked a lady the other day, "is represented by the figures of my own age reversed. He is my senior, and the difference between our ages is one-eleventh of their sum." How old are they? <\/p>\n<\/blockquote>\n

7. Final Thought: Greatness<\/h2>\n

The world's best discoveries were made along a road littered with wrong turns, insufficient knowledge and many outright failures. Don't worry if you feel like that in math class sometimes! <\/p>\n

\n

If at first you don't \t\t\t\t\tsucceed, you're like everyone else who went on to greatness. \t\t\t\t\t[Patrick Combs] <\/p>\n<\/blockquote>\n

Until next time, enjoy whatever you learn.<\/p>\n
