Quiz 2: Trigonometric Functions of Special Angles

Without using a calculator, use this applet to test your knowledge of evaluating trigonometric functions of special angles. Every angle you see will be a multiple of pi/6 and/or pi/4 radians. Angle range tested here = [-100pi, 100pi]. Be sure to input EXACT VALUES of RATIOS in the input box! Use the phrase "sqrt()" for the square root symbol. For example, type "sqrt(3)/2" for .
