In the last blog, I introduced a method for using trigonometry to find the missing side in a right-angled triangle. This blog will build on that and show you how to find the missing angle in a right-angled triangle. I would recommend reading that before this one for an introduction… Continue reading A guide to trigonometry (SOHCAHTOA) – Part 2
Following on from the previous blog on Pythagoras’ theorem, this blog will be a guide to solving trigonometry questions. This guide will show you how to use trigonometry to find a missing side in a right-angled triangle. The next blog will build on this idea and show you how to… Continue reading A guide to trigonometry (SOHCAHTOA) – Part 1
a2 + b2 = c2.That’s Pythagoras’ theorem. What it says is that in a right-angled triangle, the sum of the squares of the two smaller sides equal the square of the longest side (or hypotenuse).From my experience, most GCSE students understand what Pythagoras’ theorem is, but when it comes to… Continue reading Easy as Py – a guide to Pythagoras’ Theorem
Following on from the previous blogs about the number 6174 and the (not-so) magic number 10, here are 5 more cool maths tricks that you can use to impress your friends.Trick 1For this trick, pick a three digit number with repeating digits (eg. 222 or 999)Add up the digits of… Continue reading 5 more maths magic tricks
In this blog, we will look at distance, speed and time calculations and I will show you a handy trick that will help you to remember how to calculate them.First of all – distance, speed and time are all related. If you have two of them, you can use them… Continue reading Distance, speed and time calculations
