1. The equal sign: more trouble than it’s worth?

Suitable for: Everyone, since we all come across equal signs every day.


The equals sign causes a lot of grief. Should we replace it with more meaningful symbols?

2. Equation of Time, an application of ellipses and composite trigonometric graphs

Suitable for: Everyone. You will come across conic sections and trigonometric graphs at some point in your math career.

The Equation of Time is an interesting application of conics and composite trigonometric curves.

3. Back to school tips

Many of your are starting school again very soon. Here are some earlier articles you may find useful:

4. Friday math movie: Right brain math

Suitable for: Everyone.

right brain

Never could master those times tables? This right brain approach might be a solution for you.

5. Final thought: Just do it!

As the school year begins (for many of you), it's a good opportunity to consider how you are going to make the most of it.

The research is in: multi-tasking just means we do a lot more things, but none of them well. (See Is multi-tasking a myth? from the BBC).

Want to do well at anything (not only math)? There's a simple solution - focus.

Until next time.

HTML: You can use simple tags like <b>, <a href="...">, etc.

To enter math, you can can either:

  1. Use simple calculator-like input in the following format (surround your math in backticks, or qq on tablet or phone):
    `a^2 = sqrt(b^2 + c^2)`
    (See more on ASCIIMath syntax); or
  2. Use simple LaTeX in the following format. Surround your math with \( and \).
    \( \int g dx = \sqrt{\frac{a}{b}} \)
    (This is standard simple LaTeX.)

NOTE: You can mix both types of math entry in your comment.
