Additional Mathematics

Yesterday after tuition went to KengSein's house and guide her on add maths... And she made me realise that my form 5 add maths is so so so bad.... hahaha! especially trigonometric function! I don't even understand a single thing! While she was trying out some questions I was reading some magazines... And then later on kacau-ed her.... bwahahha... let me show you some of the pictures I took at her house.
