# Trig degrees: tangent tool

TLF ID L9115

Use a unit circle tool to explore tangent values for angles between 0° and 360°. Use the information to determine what the graph of tan Ø will look like. 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 explore the unit circle definition of tangent.
• Students explore the values of tangent (from 0° to 360°).
• Students identify discontinuities, symmetry, period and key values of the tangent function.
Educational value
• Enables students to appreciate the key features of the tangent function (from 0° to 360°).
• Provides an interactive unit circle tool to ensure students work with general definitions of the tangent function (connected to the right-angled triangle definition).
