iii) we did prove it in part i) and ii) that
h = v^2sin^2 a / 2g and x = v^2 sin2a /g
should notice that the maximum height in part iii) is H-S = h
soo H-S = v^2 sin^2 a/ 2g (1) and d= v^2 sin2a/g
= 2v^2 sina...
Some challenge questions heheh...
1.solve sin ^nx + cos^nx = 2 ^(2-n)/2
2. solve 3arctg(x) - arctg (3x) = pi/2
3. pi^/sinx^(0.5)/ = /cosx/
If u can solve them???? Well i will difinitely call u guys teacher
Im the first one to contribute some ESL resources for u guy. Im currently doing it - my weekness subject - the one will scale down my UAI :-(. Hope u guys will post more and more ESL resource...:-)

Im stuck with this dot point :( :confused . Is there anyone do Medical Physics can help me with it???
Heyyy...is there anyone out there do this option? i just started last week.
Could u guy post some notes and revisions for it please!!!!
Or advice me what points i need to remember by heart in HSC exams questions???
Thanx a lot!!!!
Im stuck with the dot point: "Compare qualitatively low Earth and geo-stationary orbits" and " Account for the orbital decay of satellites in low Earth orbit" :(
Could somebody pls help me???:confused:
