## Core 1 and 2 – Differentiation to find stationary points

Again as yesterday Core 1 and Core 2 are the same except the Core 2 questions have more complicated powers of x. It’s worth noting again that we can’t cover everything in these posts. There are some questions on increasing and decreasing functions and some applications of stationary points that I’ve not covered here. You will need to look through past papers yourself to ensure you can do all the questions.

## Core 1 and 2 – Differentiation to find tangents and normals

Core 1 and Core 2 differentiation are very similar. The only real difference is that in Core 2, x can have negative and fractional powers. There are two videos and two questions below. One of each is a Core 1 questions and one of each is a Core 2 question.

Core 2

## Core 2 – Binomial

This topic is fairly easy to start. The main thing you need to do is plug numbers into the formula. There may be some tricky algebraic manipulation that you will need to practise.

Below is a video answer to June 2013 Question 3. Take a look at it and then try another one yourself

## Why wait for me…?

In this blog are a lot of links to revision pages written by other people. That way you can revise any topic you like without waiting for me to write the next blog. I’m going to take a break tomorrow so the next blog will by Monday morning.

AQA Website

All the past papers are available on the AQA website. Just select

mathematics, A level, mathematics (6360), all available series

You can then find any paper from any year with the markschemes.

Exam Solutions Website

This is a great website that has revision videos for almost every topic. Links to the AS pages are below

Core 1

Core 2

Statistics 1

MathedUp

FMSP Revision Videos

This page just has videos for Further Maths. Included in this is some Statistics 1 videos towards the bottom of the page.

You can search these channels for any topics you are stuck on.

## Core 2 – Geometric Sequences

This final post on this topic will look at geometrical sequences. Again you need to know how to use the formulae in the formula book. One difference to arithmetic sequences is that you also have an infinite sum formula. This can be used when the common ratio r is between but not including -1 and 1.

Geometric questions can be combined with logs so come back to this topic again when you’ve had time to look at logs. As always if you need more help then just ask at our Facebook Support Group (link on the right)

## Core 2 – Sigma notation

Yesterday you looked at the basics of arithmetic sequences. Today we look at how these sequences can be written using sigma notation. The video below shows what sigma notation is and the exam questions below will be good practice.

Now try these exam questions. Any questions then just ask on our Facebook support group.
