What’s that, you cry? Algebra was bad enough, without throwing fractions into the mix? Well, unfortunately for you, it’s on the Edexcel Unit 3 spec., and you’re going to have to learn it. To find out about algebraic fractions, simplifying before multiplying, and calculations involved, read on…

Yikes. Probably the fusion of some of the nastier topics on the GCSE Maths course – trigonometry, and graphs. And you have to know how they transform, as well! But not to fear, this article is here to tell you all you need to know about trigonometric graphs – and how they transform, using the handy rules in this article here (best read that before this article). Ready? Then let’s get these graphs going on…

You might have thought transformations was as simple as translating, enlarging, rotating and reflecting. Well, maybe it is – in Year 7. For the Edexcel GCSE Maths course, you need to learn about transforming any graph – known as transforming **functions**. Confused? Don’t panic, we’re going to explain this all here – so let’s give it a go!

You’ll have almost certainly seen this stuff somewhere before – probably around Year 7, 8 or even earlier. But heading back to translations, enlargements, rotations and reflections is all important for getting those easy marks in the Edexcel Unit 3 exam – so we’re going to cover it. Ready? Then let’s go for it…

You might have thought this was done, with a quick article on simple simultaneous equations a while back. But no, they’re back, and they’re back with a vengeance. Ready to take the plunge? Here we go…

And you thought normal, straightforward, rational numbers were hard enough. Then surds came along – nasty, recurring decimals; square and cube roots, and goodness knows what else. It’s understandable that you’d be feeling a little unsure of what to do now. But really, surds are all about knowing how to manipulate them – a few handy tricks I’m going to show you here. Ready? Then let’s begin…

And you thought it was safe to go out again. No, circle theorems are not over – we’ve got to know how to prove them as well, much like many different things in Maths. And although only one is really likely to be on the exam, we’ll cover all of the proofs for the theorems that have even the slightest chance of coming up – to see these, continue reading…

Circle theorems. Ah, what a wonderful part of the Unit 3 Maths exam. Or not, as it may be. Confused between your cyclic quadrilaterals and alternate segments, or between your chords and your tangents? Don’t worry, because here, I take the plunge and give you a crash course in circle theorems. To find out, read on…

*Sorry, I couldn’t think of an appropriate image for this topic!*

Bounds? What are bounds? Bounds are actually quite a simple idea, but sometimes they can take a while to get your head around… So, with this in mind – let’s go!

**Overview**

Yikes. You thought that trigonometry was bad, and then this article came along and just told you that things only get harder from this point onwards. And they do. But not unmanageably so. This article is best visited after you’ve seen the bog-standard Trigonometry article – but if you’re ready to take the plunge, let’s get ready to move into the 3rd dimension…
