I also have another question that I need help with, I don't get how to do 5B in HSC 2006 exam

to find the area in that graph you would:
1. tan x - x (i.e. top line minus bottom line)
2. integrate that with pi/4 and 0 being your limits or whatever they're called
3. note that you get the integration of tan x from part i. of that question
and yeah that's it =)
