We’ve finished Core 1 now so why not try a whole paper and see how you go. Have a go at the paper below and then watch the video answers to see how you did.

## 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 1 – Circles continued

Here we will look at some more complicated circle questions. The videos from the previous circles blog will help.

## 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

**MathedUp**

This website has videos and practice questions for most topics of AS Maths. A good place to start is on his A level takeaway page.

**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.

**Good YouTube channels**

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

## Core 1 – circles

Below is a set of videos that will help you revise circles. Have a look at as many as you need and then have a go at the exam questions. If you get stuck then just ask in our Facebook support group.

## Core 1 – discriminant

Yesterday we looked at solving inequalities. This topic is often combined with use of the discriminant. The discriminant (D = b^{2} – 4ac) tells you how many roots a quadratic of the form ax^{2} + bx + c = 0 has.

if

D > 0, there are two distinct and real roots

D = 0, there is one repeated root

D < 0, there are no real roots

June 2013 question 7 – answer here

Most question though are harder than this, take a look through some of these videos and then try the exam question below.

January 2013 Question 8 – answer here

## Core 1 – Quadratic Inequalities

This topic is something that students often get wrong. The main thing to note is that it is really helpful to draw a graph. If the question is an inequality then it is likely that the answer will be an inequality.

These kind of questions almost always come up with the discriminant, which will be tomorrow’s lesson. For the moment just try the part questions below and we’ll look at whole questions next time.

## Core 1 – Straight lines 2

Today we will look at more complex straight line questions. Have a go at the two questions below, watching the videos where you need to. The questions involve a knowledge of parallel and perpendicular lines as well as how to find intersections using simultaneous equations. New College students can get more help at our Facebook Support Group.

## Core 1 – simultaneous equtions

Today we will look at solving simultaneous equations. There are two methods you should be familiar with. Have a go at the questions below and watch the video if needed.
