A-level Maths (English curriculum)
This tutorial follows on from “Working with surds” and covers skills needed for Higher GCSE and beyond. If anything in this article leaves you feeling a bit lost then go back and work through the previous one first. Rationalising the…
For Higher GCSE and beyond, you need to be able to work with surds. This is Part 1 of a two-part series. Part 2 – on rationalising the denominator – can be found here, but make sure you’re comfortable with…
This article is part 3 of a series on the aspect of Calculus known as Differentiation; for the preceding parts seePart 1 (introduction)Part 2 (stationary points)It will be relevant to you if you are studying any of: … or any…
This article is part 2 of a series on differentiation; part 1 can be found here. It will be relevant to you if you are studying any of: … or any other course that involves Calculus. In part 1 we…
This article will be relevant to you if you are studying any of: … or any other course that involves Calculus. Calculus is a major branch of mathematics consisting of two areas: differentiation and integration. Differentiation involves working with rates…
Over the years that I’ve been maintaining this blog, I’ve posted over 30 maths tutorials on specific topics. Since at the time of writing I’ve just passed the 4-year mark, I thought that now would be a good time to…
This is the final instalment of my series of tutorials on straight line graphs, and follows on from “Working with a coordinate grid“, “Straight line graphs Part 1” and “Straight line graphs Part 2“. We’ve covered most of the Foundation…
This is the third of my series of three articles on hypothesis testing for A-level Maths, and covers hypothesis testing for pmcc (the product moment correlation coefficient). The first instalment introduced the concept of hypothesis testing and covered hypothesis testing…
This tutorial follows on from “Working with a coordinate grid” and “Straight line graphs Part 1“. We’ve covered the basics of straight line graphs – enough to get you up to about Grade 3/4 level at GCSE – and now…
The English A-level Maths specification includes “integration as the limit of a sum” and “Fundamental Theorem of Calculus”. This article explains these expressions. Using strips to estimate the area under a curve To estimate the area under a curve, we…
This tutorial follows on from “Working with a coordinate grid“, where we covered plotting coordinate points and the equations of vertical and horizontal lines. We’re now moving on to look at plotting other straight line graphs, and understanding the general…
This is Part 3 of a three-part tutorial on graph transformations, and covers compound transformations. If you haven’t already worked through Part 1 and Part 2 then I recommend you look at those before trying to make sense of this…
This is part 2 of my series of three articles on hypothesis testing for A-level Maths. The first part can be found here; it gives an introduction to the concept of hypothesis testing and covers the Year 1 topic of…
This is Part 2 of a three-part tutorial on graph transformations; Part 1 can be found here. If you haven’t already worked through Part 1 then I recommend you look at it before trying to make sense of this one!…
In my tutoring, the topic of graph transformations is one that almost every Higher GCSE, IGCSE or A-level student wants to spend time on, so I thought I’d use it as the subject of a series of blog posts /…
In the first year of the A-level Maths course you need to be able to carry out a hypothesis test to judge whether a Binomial probability has (probably) changed. In the second year, hypothesis tests are required (1) to decide…
The A-level Maths specification requires you to work with formulae for compound angles – sin (A ± B), cos (A ± B), tan (A ± B) – and use these to derive and use a range of double angle formulae,…
All the Casio Classwiz calculator models – both the original “X” and the new “CW” models – feature ratio mode, which didn’t exist on their predecessor the fx-83/85 GT Plus. Although it’s perfectly possible to get by without ever using…
In early 2023, Casio replaced the popular Classwiz fx-83/85GT X and fx-991EX calculator models with the Classwiz fx-83/85GT CW and the fx-991CW. The change is a lot less trivial than you might think! A short (recent) history of Casio scientific…
In the first year of A-level Maths, all the vectors you deal with are given to you in component form, i.e. as two perpendicular components, e.g. $\begin{pmatrix}2\\-3\end{pmatrix}$ or 2i – 3j. In the second year, however, you’re more likely to…
This article, on equilibrium and resultant forces, follows on from my recent post on Forces and Newton’s Laws of Motion, and covers part of the Mechanics content of the first year of A-level Maths – though I’m sure that a…
This is part 3 of a series covering the mathematical notation you need for A-level Maths. Click the links below for the previous parts:Part 1: set notation and miscellaneous symbolsPart 2: other Pure Maths notation This final instalment covers vectors…
Much of the mathematical notation that you need to know for A-level, you’ll already have come across at GCSE, but there are some symbols that you may not be familiar with and others that you certainly won’t have used before…
