Day: Thursday
StudentsPresent: Solomon, samuel , Boni
Teacher: Jimmy
Subject: Math
Topic: Trigo
Concepts taught:Reference angle , pythagorean theorem , addition forumlae, product formulae, R formulae,.
Comments on students:Explained to them that cos(2x+67.38) can be varied which leads to a corresponding change in F(x).In a way we can find out the max and min value of f(x). Samuel and Solomon was able to digest this concept. Boni took quite some time to sink in.· Proceed on to try A2.11.All of them were stucked initially. Explained on white board that one must first simply the equation to only non -power trigo functions. Zoomed in on how to simplify 4sin2xcos2x and 6 sin square2x to sin and cos function only. Proceed on to apply R formula. Solomon and Samuel was able to adjust the resultant R formula to the final question. Went on to illustrate on the usage of product formulae on question A2.15.3 of them knows where to look for from the formula list. Samuel was able to do this question. His only problem lies in his messy hand writing which not only affects his overall presentation but also his judgement on the flow of work· Went to do egA2.2 Hinted to them the initial approach of drawing the triangle. Solomon and Samuel was able express to work out the answer.
Improvement: samuel's handwriting can improve his overall presentation and his own judgement.
