\n===========================<\/p>\n
Many of you have math exams in the next few weeks. Some students go about exams all wrong.<\/p>\n
Things I always did to ensure I was in peak form for exam day:<\/p>\n
* I would make time for exercise<\/strong> (increased blood flow to the brain helps learning. The mind-body connection is important).<\/p>\n * I would get a decent sleep<\/strong> (last minute cramming is very dangerous - I only did it once and almost fell asleep in the exam). Sleep is essential for problem solving - and for learning.<\/p>\n * I would eat well<\/strong>. If you have an afternoon or evening paper, avoid the carbs - they make you more sleepy.<\/p>\n * I would try to learn all formulas<\/strong> (even though they were going to give us a formula sheet in the exam). Then I would have a much better idea about which formula to use in which situation.<\/p>\n * I never rote-learned<\/strong> answers. It is so obvious to a marker if you are giving an answer to some question which is not there!<\/p>\n * I would circle key words<\/strong> in the question (don't try to PROVE something when they ask you to SOLVE it)<\/p>\n OK, enough of sounding like your mother. Good luck in your math exam.<\/p>\n This week is Earth Day (22 April). It is probably one of the most significant Earth Days in years.<\/p>\n We finally have broad agreement that the climate is changing. What is not so certain is how we should respond.<\/p>\n A hint to those of you deciding on your future careers...<\/p>\n Over the next few decades, there will be many job openings that involve mathematics:<\/p>\n * Climate modelling, Recent updates to the IntMath site have included:<\/p>\n 1. A new page on Biorhythms<\/a>:<\/p>\n 2. Updated Counting and Probability<\/a> chapter:<\/p>\n 3. Updated Plane Analytic Geometry<\/a> chapter:<\/p>\n Let me know if you have any further suggestions for improvement.<\/p>\n 1) EARTH DAY AND THE SOUTHERN OSCILLATION INDEX<\/a> 2) TRIG GRAPHS - HOW DO YOU FEEL TODAY?<\/a>EARTH DAY<\/h2>\n

LATEST FROM THE MATH BLOG:<\/h2>\n
\nAustralia is suffering the worst drought in 100 years. The
\nSouthern Oscillation Index helps Australian farmers to predict
\nrainfall and temperature.<\/p>\n
\nBiorhythms claim to tell us when we should feel good and what
\ndays to stay in bed. They are an interesting application of sine
\ncurves with different periods.<\/p>\n
