Mathematics Worksheet

26 people in the class have received the trigonometry worksheet for maths. If you are one of the 12 that haven't received it, here it is for your downloading and viewing pleasure. Deadline is Friday (I doubt it, but that's what Ze Jun says).

Meanwhile Chinese tomorrow from 8am to 10am and Physics from 1030 to 1230 tomorrow.

*THE UPLOAD SCREWED UP SO HERE I AM TYPING OUT THE QUESTIONS*
