  • finding coeffecients in expansions
• fraction laws
• index laws
• differentiation
  • quotient rule
  • product rule
• polynomials
  • polynomial odd/even graph behaviour

    • ${\alpha }^2+{\beta }^2+{\gamma }^2$ formula
      • 
    • $\frac{1}{\alpha }+\frac{1}{\beta }+\frac{1}{\gamma }$ formula !!!!!
      • $\frac{\alpha \beta +\alpha \gamma +\beta \gamma }{\alpha \beta \gamma }$
• compound angles
  • split up into exact (friendly) values
  • interpret from formula sheet (flip +s & -s)

• trig
  • t formula
• inequalities
• combinatorics
• rates of change
• The symbol ∈ indicates set membership and means “is an element of”
  • e.g.
• find y asymptotes:
  • limit as x → infinity, divide all terms by highest power of x and just ignore terms with x
