This software can be used for the following purposes:

  • Demonstration and explanation of the concept and meaning of the basic trigonometric functions sine, cosine and tangent during the step by step animation using a unit circle and visual-dynamic tools.

  • Demonstration, explanation and practice of the trigonometric relations in a right-angled triangle and their usage in problem solving.

  • The Law of Sines, its meaning and use for problem solving, such as finding missing sides and angles in any triangle.

  • The Law of Cosines, its meaning and use for problem solving, such as finding missing sides and angles in any triangle.

The software provides the user full control of the animation:

  • Data can be accumulated in the Data Table.

  • The animation can be activated for positive or negative values of angles.

  • The scales can be adjusted using units of degrees, multiples of π or radians.

  • Secondary units can be added to the horizontal scale.
