Learning objects Trig degrees: tangent to 360: demo

TLF ID L9118

Watch a demonstration showing how tangent is defined in the unit circle. Connect this definition with the right-angled triangle definition commonly used in right-angled triangle trigonometry. 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 view the unit circle definition of the tangent function.
  • Students view the connection between the unit circle definition of tangent and the right-angled triangle definition of tangent.
Educational value
  • Demonstrates the definitions of the tangent function (from 0° to 360°).
  • Enables students to use the unit circle tool to explore sine, cosine and tangent values in different quadrants.
