Day: Thursday
Students present: Solomon, samuel , Boni
Teacher: Jimmy
Subject: Math
Topic: Trigo( 2nd lesson)

Concept taught:More examples on R formulae , addition formulae , product formulae.(A2.13,2.14,,2.15,2.17,A2.7,eg.2A(3,4,5(ii),6,8(iii))

Comments on student: Boni knocked her head onto one of the book shelf which results in her emotions becoming unstable.We carried on with the lessons.All were able to prove lhs=rhs for eg 2.13.Revised with them ATSC once more.They tried A2.14 and realised that the order in the addition of sin is important .Tried q4 on page 393 n were able to reduce the 2 trigo functions into a single trigo function using the R formula.They proceeded to solve the equation for x using what they have been refreshed on ASTC. Went on to prove 5(ii).Solomon was able to develop left hand side and right hand side til they reaches a consensus.Explained to them that they will still score some marks if they do it this way but not full.All 3 later realised that it can be solved by changing the cot into cos and sin functions on the right hand side.Went on to do question 8(iv) , able to do it confidently:)
Improvement: Boni needs to practise more.Solomon still needs to restyle his presentation.Samuel 's improving fast.
