Weekly Reflection WW02 - 4E3

The students are learning about Trigonomterical Ratios. With relation to sketching of curves, I highlighted to them the important points to note when doing such sketch. Walking around, I noticed that most of them are able to do so. However, some questioned why the solution of cos2x=sinx need two curves. I brought them back to the topic on graphical solution. They understod better the concept. Class test next week will help confirm this.
