Re: HSC 2017 Maths (Advanced) Marathon y = 3x³-6x²+4x+7 y’ = 9x²-12x+4 For S.P. y’=0 9x²-12x+4=0 x= 2/3 y=71/9 Therefore S.P. at (2/3 , 71/9) For I.P y′′=0 y′′=18x-12 18x-12=0 x=2/3 y= 71/9 Therefore I.P. at (2/3 , 71/9) Soz don't have time

Hey Guys I am currently in year 11 doing 3u maths I want to do 4u next year And I really like and enjoy maths I was just wondering how to get an E4 in Ext 2 and Ext 1? Like if u guys have any tips tell me I will really appreciate it THANKS:)

Hi Guys I am looking for HSC textbooks for physics and chemistry as a pdf. I am looking for dot point, spotlight and excel for chemistry, I really need Jacaranda chemistry. For physics, i am looking for dot point and spot light. all for HSC Thanks.

Hey Guys! I am a student currently studying in year 11. I will be making notes for HSC next term. Not sure how to make my notes. So should I make notes on computer (word) or a physical book (handwritten notes). Thanks.

Thanks:)

Does anyone have worksheets based on this equation: q=-mCΔT ------ with answers (doesn't really matter) And also if you guys have any worksheets based on other calculations in chemistry, please upload it. I will really appreciate it. Thanks.
