Mathematics / Level 10A / Measurement and Geometry / Pythagoras and trigonometry
Content description
Use the unit circle to define trigonometric functions as functions of a real variable, and graph them with and without the use of digital technologies
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
