Bayesian Probability

August 29, 2010

For those of you who wish to try and understand Bayesian Probability, Congratulations and Commiserations. Congratulations because you are doing the right thing, commiseration because I know what sort of headache you are going to have in about 2 hours….

Troublesome, tricky triangles of terror!

August 8, 2010

Triangles are the simplest of geometrical shapes – three connected straight lines form a triangle. Of course, we need ways to classify the different possible types of triangle (right-angled or not, equilateral, isoceles or scalene, etc.)

But that is old – you learned that information in primary school – early in secondary school you learned about the angles (summing to 180, acute, obtuse, complementary, etc). This year we want to be able to identify if two triangles are similar (same internal angles, different side lengths) or congruent (exactly the same – i.e. same sidelengths and same angles.)

Mathematical limbo – or getting under the line!

August 8, 2010

Have you ever tried to limbo? Bending over backwards, contorting yourself to get under a low stick? You know you have – if you think you haven’t you’re probably just repressing the memories!

Calculus is just the same, except the limbo stick is a function (possibly on fire, and definitely covered in sharp spikes). Instead of bending over backwards and ruining your spine, you have to twist, torment and contort your brain in order to force the function to reveal the area between it and the axis. But don’t worry – you can do this – after all, you’ve survived Maths Methods this far!
