Quiz 1: Trigonometric Functions of Special Angles

① This interactive quiz demonstrates evaluating trigonometric functions for special angles (multiples of π/6 and π/4 radians) over a range from -12π to 12π, providing immediate feedback. ② Core math concepts include sine, cosine, and tangent defined via the unit circle, exact values for special angles, and radian measure with periodicity. ③ Construction highlights: uses GeoGebra commands such as RandomElement, Numerator, Denominator, Random, Textfield, and SurdText to generate random numerators/denominators, an input box (InputBox1) for answers, a button (button1) to generate new questions, and multiple text objects (text1–text9) to display prompts and feedback. ④ Suitable for high school or pre-university students learning trigonometry, ideal for classroom quizzes, self-study, or teacher-generated exercises to reinforce memorization and computation of special angle trigonometric values.
