use the unit circle to define the simple trigonometric functions of y=sin(x), y=cos(x) and y=tan(x) as functions of a real variable, and graph them with and without the use of digital tools
Elaborations
establishing the symmetrical properties of trigonometric functions
investigating angles of any magnitude
understanding that trigonometric functions are periodic and that this can be used to describe motion
identifying points on the unit circle via arc lengths in radians, which correspond to specified values of the circular functions sine, cosine and tangent
