Homework 2-4 on Integration<\/b> was due in on Tuesday 26th November.<\/p>\n
We dealt with Chapter 10 – 3D Trigonometry<\/i> as a prelude to Chapter 11 \u2013 Addition Formulae<\/b> and we quickly covered the 4 expansions for sin(A\u00b1B) <\/i>and cos(A\u00b1B)<\/i> with numerous questions getting practice on these. I pointed out that this style of these early questions tend to occur in the Objective questions and are worth 2 marks each and I reminded the class that everyone needs to have learnt the exact values for sine <\/i>and cosine <\/i>for angles of 30o<\/sup>, 45o<\/sup>, 60o<\/sup>, 90o<\/sup> and multiples thereof as they were told to do when we did Unit 1. We also covered the applications of the addition formulae.<\/i> This took us up to and including Ex11F and the work can be found on the MyMaths website under Library \u2013 A Level \u2013 Core 3 \u2013 Trigonometry \u2013 Addition Formulae.<\/p>\n The class were issued with a Practice NAB to be completed by Friday 6th December when we will go through it all with guidance on the threshold scores and how the marks are awarded. The class were also reminded that after they have sat the minimum competence NAB that they will then be given the Extended Unit Test to more accurately see how well each individual is coping with the course thus far.<\/p>\n <\/p>\n","protected":false},"excerpt":{"rendered":" Homework 2-4 on Integration was due in on Tuesday 26th November.
