Quiz 1: Trigonometric Functions of Special Angles (Autoevaluable)
Modificación de un archivo de Tim Brezinski.
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 = [-12pi, 12pi]. 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 . You can complete only 4 problems. For an applet that generates questions similar to these for angles between [-100pi, 100pi], click here.
