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…

In this tutorial we’re looking at working with a coordinate grid: what it looks like, terminology and plotting points, and the equations of simple vertical and horizontal lines. Once you’re comfortable with this basic content, you can move on to…

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 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 what will eventually be 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…

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…

Directed numbers are something that a lot of people find confusing. I hope that this article will help you to get your head round them! What are directed numbers? “Directed numbers” means positive and negative numbers. “Positive” or “negative” describes…

Something a little different this month, since it’s the summer holidays. This year I’m running a stall at a couple of local carnival-type events to promote my theatre company (STAMPS)’s show and use some carnival games to fundraise while I’m…

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…

For Foundation GCSE you just need to know what equations and graph shapes represent direct and inverse proportion, and work with equations given to you. That’s all covered in a previous article which you can find here. For Higher you…
