1. Revision suggestions for calculator paper 2009
D C B A
Angle properties – Z and X Pythagoras Trigonometry Sine rule and cosine rule
angles SOH CAH TOA
Internal and external angles of Volume of prisms Reverse percentages Area of triangle using
polygons ½ ab Sin C
(a and b must ‘trap’ angle C)
Area and circumference of a Similar shapes – angles the % increase/ decrease Vectors
circle same, sides in the same ratio = (difference / original) ×
A = πr² C = πD or C = 2π r 100%
These must be memorised!
Area of compound shapes – Mean from grouped data – Compound interest Rationalising the denominator
rectangles and circles or find the midpoint × frequency
triangles put together etc
Fractions Changing the subject of a Quadratics Quadratic formula
formula
Ratio Speed-distance graphs Recognise shapes of graphs Stratified sampling
Which is the better buy… Compound measures Moving average Recurring decimals
Density, speed etc.
Stem and leaf Bearings Similar shapes Fractional and negative indices
Enlargement Trial and improvement Regions – using inequalities Cones and spheres
Pie charts Expressions – identify length,
area and volume
Scatter graphs Trial and improvement
