Learning objects Trig degrees: sine to 360

TLF ID L7844

Use a unit circle tool to explore sine values in different quadrants. Determine the sin Ø values for angles between 0° and 360°. Observe the symmetry and patterns of the functions to predict the behaviour of sin Ø in different quadrants. Observe the graph animate and visually connect it with the unit circle tool and table values. Extend sin Ø for angles beyond 360°. Find out how trigonometry relates to the real world. This learning object is one in a series of nine objects. Three objects in the series are also packaged as a combined learning object.

Educational details

Key learning objectives
  • Students apply the unit circle definitions of the sine function.
  • Students interpret a graph of sin Ø, from 0° to 360°.
  • Students identify patterns and symmetry of the sine function.
Educational value
  • Enables students to compare and understand the key features of the graph for the sine function (from 0° to 360°).
  • Provides an interactive unit circle tool to ensure students work with general definitions of the sine function, connected to the right-angled triangle definition.
  • Includes challenges that highlight the symmetry and patterns of the sine function.
  • Contains associations with real world periodic phenomena that are modelled with trigonometric functions.
