I am offering tutoring for 2 and 3 unit maths for $13.50 per hour to anyone who lives around Caringbah. I can provide study resources and outside tutoring sessions you can email me with problem questions.
I did my HSC this year and based on my school trial results I was given a place at UOW...
I tried to work out the surface area of a sphere through calculus and came up with pi^2 * r^2 and I cant see any errors in my working. Can you see where Ive gone wrong? (see attachment)
Thanks.
