Re: Where can I get Fitzpatrick book? err i got mine at dymocks at parra westfield 2U and 3U each for round 70 bucks each...can also try cambridge : D

randomness instead of subbing in 1-cos^2 A for sin^2 A you could have just gone sin^2 A + cos^2 A = 1 its faster thats all. :D err i have to learn how to use this latex thingy now :l

because most of us also have a life? :/

LHS = (sin^2 A + 1 + 2cos A + cos^2 A) / [sin A(1 + cosA)] LHS = (2 + 2cos A) / [sin A(1 + cos A)] LHS = [2(1 + cos A)] / [sin A(1 + cos A)] LHS = 2 / sin A LHS = 2cosec A LHS = RHS hope this helped

high school speeches are just essay read out loud so saying stuff like that IMO is kinda time wasting, what they are looking for is analysis and how u are able to tie it to your thesis.

natural ability to understand and do harder maths
