In this blog, I will explain one of the most common mistakes I see made by GCSE maths students. We have already seen how to solve equations, but you also need to be able to solve inequalities in GCSE maths. What is an inequality? There are two inequality signs you… Continue reading The Problem with Solving Inequalities in GCSE Maths
Triangles come up a lot in GCSE mathematics. And there are a variety of different methods that can be applied to questions. If you are given a triangle with a missing side or angle, there are four different methods that you can use to find the missing information (bold means… Continue reading Triangles in GCSE Maths
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
