Solving Trigonometric Equations-Problem Solving

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)
