•
Sine/Cosine rule
•
Vectors
•
•
Some calculation where you are required to write down all of the digits on your calculator.

Drawing the graph where the equation is given
•
Working out the equation of a line parallel to a given line
•
Working out the equation of a line perpendicular to a given line

•
Drawing the graph where the equation is given
HINT: Use TABLE mode (MODE + 3) on the fx- calculators
•
Simplifying an algebraic fraction, e.g. (x2-5x+6)/(x2-9)
(factorise the numerator, denominator, then cancel down)
•
Simultaneous equations
(either two linear, or one linear and one curve)
•
Trial and improvement
•
•
Bearings (often with trigonometry)
•
Construction

Similar shapes and solids
•
Trigonometry (SOHCAHTOA, sine rule, cosine rule)
•
Vectors
•
•
Estimate of the mean
•
Histograms
1.
One measure of average, e.g. compare medians, then interpret the result in the context of the question.
2.
One measure of spread, e.g. compare the range or interquartile range then interpret the result in the context of the question.
