sorry guys, first, Liang jie is lazy, Liang jie is busy and Liang jie is sibeh worry on his PMR students.
we need some changes in our PMR syllabus planning.
Dear all PMR tutors. please TEACH trigonometry USING material Photostat by Liang Jie at the top of the shelf, if you cant find Please Let me know, i will let you know which book.
what to teach in trigo?
we just have to teach this.
1. TRIGONOMETRY is merely a part 2 of Pythogoras Theoram and combination of Form 2 Ratio, we are still learning RIGHT ANGLE TRANGLE, and must let them understand how to differentiate where is OPPOSITE, ADJACENT and HYPOTENUSE.
2. by using the paper i photostat, ask them to write down all the O, A, H on every right angle triangle in EVERY single question.
3. Start Asking them to REMEMBER this 3 formulae
TOA 大
CAH 脚
SOH 嫂
or
SOH
CAH
TOA
a handsome guy name haha (by yi shuian)
tell will ask what is theta "θ", is just an UNKNOWN for ANGLE. YOU DONT KNOW THE ANGLE, instead of use x or y, those alphabet, we use theta, looks PROer. haha
4. then start question with them. applying the O,A,H into TOA, CAH, SOH.teach them how to apply ya! and look properly ohh, You need Ratio.
5. Please call Liang Jie (017-381 7670) when u READ this, earlier on Monday Morning! i NEED TO LET YOU KNOW SOMETHING.
