# Trigonometry: assessment

TLF ID L9180

Test your understanding of angles and their sine, cosine and tangent values. Use a unit circle tool to find sine, cosine and tangent values in different quadrants. Use the tool to find the angle when given sine, cosine or tangent values. Determine the values for angles between 0° and 360°. Solve problems by using the unit circle tool to work out unknown values. There are 21 questions. At the end of the assessment, view and print a report on your work.

#### Educational details

Key learning objectives
• Students use the unit circle tool to find the value of sine, cosine or tangent of a specified angle.
• Students use the unit circle tool to find the value of an angle given sine, cosine or tangent for that angle.
• Students identify the key values and relationship between the value of an angle and the unit circle ratio for angles between 0° and 360°.
Educational value
• Assesses student understanding of three trigonometric functions (sine, cosine and tangent) from 0° to 360°.
• Provides an interactive unit circle tool, enabling student to answer questions.
• Includes a printable report of the student's performance.
