This site provides information on sine, cosine, and tangent. Lengths of the sides are discussed and many diagrams/tables are shown.

A slide show presentation which shows how component parts can be used to determine a vector. It also introduces trigonometry functions to show how vectors can have rotational directions.

Three trig tables are provided for student and teacher reference. The first table lists the sine, cosine, tangent, secant, cosecant, and cotangent values of all whole-number angles from 0 to 90. The radian equivalent (to four decimals)...

In Spanish. Play submarine by using trigonometry, learn the law of sines and cosine, build an instrument to measure angles and distance and find out who was the father of Trigonometry.

Use these interactive activities as a supplementary material to visualize some basic concept of Trigonometry.

Introduction to right triangles and how to solve them using trigonometric functions. Very nice interactive demonstration of what happens when the angle measurements change and how it effects the calculations. This visual might be just...

Learners explore the special angles for the six trigonometric functions. The special angles can be used to solve trigonometry problems. The table gives the values of sine, cosine, tangent, cotangent, secant, and cosecant for special angles.

Definition and description of vectors. Diagram included. This site only covers the most basic aspects of vectors.

This resource contains relevant information regarding to complex roots that includes formulas and graphs.

This lesson will illustrate how to use a calculator to find the value of a trigonometric value. It is 2 of 5 in the series titled "Trigonometric Values from a Calculator."
