- index laws
- x^1/2 = squ.
X
- (X^n)^m =
x^nm
- x^-1 = 1/x
- x^1/x^0.5 =
x^1-0.5
- expanding and factorising
- surds
- rationalising
- cancelling down large
surds
- Dividing surds
- Quadratic equations
- completing the square
- 2x^2-4b+c.
2(x^2-2b)+c,
2[(x-b)^2-b^2] + c,
(x-b)^2-2(b^2) +c
- provong a point lies on a curve
- the discriminant
- finding discriminant, b^2 -4ac = 0, =x
- no real roots
- sketching quadratics
- good at recognising
unhappy and happy
parabolas
- simultaneous equations
- one linear and quadratic
- inequalities
- rearranging linear equalities
- equalities with greater AND equal to
- forget to put the sign
down
- forget what the sign
means
- number lines
- Not knowing if it is one equation or two
- knowing that if k < 0 k = 35 is
not a value
- sketching cubics
- when x
repeats
- Transformations
- sketching y = k/x
- finding x co-ord
- intersecting graphs
- number of real solutions is
the number of times the
graphs cross
- finding area between two
lines
- prooving two graphs
do not intersect (
beast square has a
negative number)
- finding points of
intersection with algebra
- Equations of lines
- y-b = m(x-a)
- finding the length between two points
- parallel and perpendicular
- good at finding perpendicular gradient

- arithmetic sequences
- Making expressions
- "show that"
- working backwards from a equation
- Sum equation
- recurrence relationships
- finding another value

- make simultaneous equations with two sequences
- when sum is larger than
acutal value and using <
to find answer
- sequences and series problems
- recognise that 2000 is the first value and not 0 like a
baffoon
- differntiation
- squared equations
- dividing
- tangents and normals
- normal gradient is perpendicular
- leaving questions in ax + by + c = 0 when asked
