In Singlish, we called it "Jia Lat" aka 1 Difficult, troublesome. 2 Severe, to a great extent; transf. very bad, terrible." Adopted from singlishdictionary.com
I finally took the "courage" to face this demon & guessed what! I conquered it within 30 minutes using sheer eye power! Read on for a 3 minutes summary on this topic [Read more...] about E-Math Note : Congruency Triangle Tests
For those in Sec 3s, you will be learning more about Quadratic Graphs. Not so much of the drawing like in Sec 2s, but more of indepth understanding.
A quadratic graph typically is either a smiley face :) or a sad face :( some prefer to call them U or n shape.
Q1: Do you know how to tell the "mood" of the quadratic graph given its equation? Be very speific to ensure crystal clear understanding.
Eg :) or :(
Another TIP for students taking Elementary Mathematics (E-Math)
Qn: Expand and Simplify the following:
Method 1 : Expansion using one of the Algebraic rules
Did you see what is not right?
Method 2: Recognizing
