[J1 Maths PMCians] Graphing Techniques 3: Transformations


What we did in 2 hours:


We covered how replacing x or y changed a graph in two main ways: Translating and Scaling. Also, given a single expression, how to identify the correct sequence of transformations.


What you take home:


The daily dose has been given out, do try out the questions you’re familiar with!

Special Mention:


This week we will finish up Transformations, as well as get started on a new chapter, Functions.


See You and Stay Healthy!

[J1 Chemistry PMCians]


What we did in 2 hours:


We started to look at interactions between multiple atoms in the chapter of Chemical Bonding. We started off easy with O Level knowledge and started building off from there and worked towards drawing dot-and-cross diagrams for simple discrete molecules.



Next lesson, we shall use our techniques in drawing dot-and-cross diagrams to find out the bond angles and molecule shapes using the VSEPR theory.


Enjoy this song on Chemical Bonding!


See you in class next week!
