Always great to practise as many past papers as possible (esp. HSC past papers) Don't try too old ones..(like 1960s...). Perhaps, if you have time, try from 1980s if not 1990s at least
try from about 1984/86 onwards (don't try the first 3 years of the 80s as different syllabus)
you're best bet is 1995 onwards.

can anyone predict which past paper will be similar to the 2014 hsc?
by analysing trends.

Inequalities:
1. if triangle is <0, roots are real, rational and equal
2. If triangle is =0 roots are unreal and unrational
3. If triangle is >0 roots are unreal, irrational and unequal

Integrals:
{x^2 = (x^3)/2

Decay:

Change K value always to -t!!!!

Exchange:
At Rest V=0 (ONLY WHEN x[exponential] APPROACHES POSITIVE)
Initally t= 0 when t satisifies the domain
Origin x[exponential]=0 only when velocity and acceleration has been adapted
This is pretty much all rubbish, of course.
