Rates of change questions normally involve three variables: Time t and two others such as Volume and Length. When a question asks you to find a rate of change it means find the derivative with respect to time.
The general motion questions on past Edexcel papers often involve the concept of impulse which is no longer on the syllabus. The following 10 MEI questions are perhaps a better guide as to the type of question we can expect on this topic.
Here is a substantial 54 mark homework on Edexcel Connected Particle Exam Questions. My Year 12 class are doing it this week. If you would like to sharpen up your knowledge and skills in this area you could complete it and hand in next Monday. I would mark it and return it to you on Tuesday.
Once we have completed the 8 Mechanics 1 papers we will concentrate on Statistics 1 papers to consolidate knowledge of topics introduced earlier in the course.
Some questions have been annotated 'No longer on Syllabus'. Miss those questions out.
Other questions are on correlation and regression. If you are supplied with tabulated bivariate data you can attempt these on your calculator. However, if you are given summary statistics for the data you can either miss the question out or, better still, use the formulae below to attempt the questions to increase your insight into correlation and regression.
You should all have a paper copy of the Mech 1 January 2009 paper. Please complete and hand in first lesson back on Monday 25 February. In case you lose your hard copy here is one you can download:
View this as an opportunity to consolidate your knowledge of Mechanics topics that were introduced earlier in the course. Questions on topics that have been moved to Further Maths have been identified for you to omit.
Aim to complete two papers per week for the next four weeks. Once this work is complete we will do a Mech 1 paper under exam conditions.
This is the final element of the support for mock exam preparation. The question concerned is 'Calculus Associated with a Cubic'.
Though most of the marks are for problem solving with standard calculus for polynomials the first 3 marks are concerned with a general point of inflection. This has not been examined on our old MEI syllabus and I can find no mention of it in our new textbooks. I have recorded a 10 minute lesson which will hopefully help you get to grips with it.
This is a very important topic. Historically, it has been heavily examined by Edexcel. For example, on the June 2013 Core 3 paper there were two questions on Functions accounting for 18 of the 75 marks on the paper. Further down this web page you completed Functions questions from 2008-10 (blog entry dated 21 Nov 18). The questions supplied here are taken from 2011-13 papers.
