Trigonometry Equations Critical Thinking Problems and
step-by-step solutions.
Students think critically to demonstrate knowledge
• Trigonometry involves the unit circle of cos θ, sin θ and tan θ and
periodicity using degrees and radians.
• Apply the appropriate formulas and use mathematical strategies to
solve equations involving trigonometric functions algebraically.
Also comply with Australian Curriculum:
- Understand the unit circle definition of cos θ, sin θ and tan θ and periodicity using radians (ACMMM034)
- Recognise the exact values f cos θ, sin θ and tan θ at integer multiples of π/6 and π/4 (ACMMM035)
- Identify contexts suitable for modelling by trigonometric functions and use them to solve practical problems (ACMMM042)
- Solve equations involving trigonometric functions using technology, and algebraically in simple cases. (ACMMM043)
