MATHEMATICS Overview
Trigonometry
Identify right angled triangles, naming sides of right angled triangle, find
missing sides a using the 3 basic trigonometric ratios sine, cosine and tangent
and finding angles using inverse trigonometric ratios, Pythagoras theorem,
use Pythagoras theorem for finding hypotenuse, finding lengths in a isosceles
triangle, finding distance of chord from center of circle.
Statistics and probability
Arithmetic mean, mode, median, range, frequency tables and bar charts,
grouping data, continuous data, collecting information, probability of an
event, express probability as a fraction, probability of an event that does not
occur, finding probability using possibility space.
Problem solving techniques
Solve word problems, choosing the right operation in different word problems,
convert word problems to mathematical sentences.
