Tests by topic
Tests for this topic
Grade 9
Applications of trigonometry
Dynamic height, distance, slope, shadow and motion problems using trigonometric ratios.
Grade 10
Unit circle and obtuse angles
This test uses the unit circle to determine trigonometric values. Tasks cover quadrants, signs of sine and cosine, obtuse and supplementary angles and checking whether a resulting value is reasonable.
Grade 10
Sine and cosine laws
This test applies the sine rule, cosine rule and the trigonometric formula for triangle area. Students select a suitable rule from the given information, calculate sides or angles and assess whether a solution is geometrically valid.
Grade 11
Trigonometry on the Unit Circle
This test explores angles of any magnitude and direction and their representation on the unit circle. Tasks cover coterminal-angle reduction, periodicity and the use of inverse trigonometric functions.
Grade 11
Trigonometric functions and equations
This test covers graphs, periods, ranges and signs of sine, cosine and tangent functions. Tasks also develop solution of elementary trigonometric equations and selection of solutions within a stated interval.
Grade 12
Trigonometric identities and equations
This test applies fundamental trigonometric identities and methods for solving equations. Students write general solutions, use periodicity and select the values that belong to a specified angular interval.
