A SHORT COURSE IN TRIGONOMETRY - David Joyce
http://aleph0.clarku.edu/~djoyce/java/trig/
What is Trigonometry? Trigonometry began as the computational
component of geometry. One statement of plane geometry says
that given one side and two angles of a triangle, the other
two sides and the remaining angle are determined. Trigonometry
includes the methods for computing those other two sides.
(The remaining angle is easy to find since the sum of the
three angles equals 180 degrees.)
Joyce organizes his course around these headings:
- Who should take this course?
- Applications of trigonometry
- What is trigonometry?
- Angle measurement
- Chords
- Sines
- Cosines
- Tangents and slope
- The trigonometry of right triangles
- The trigonometry of oblique triangles
- Summary of trigonometric identities
- Polar coordinates (yet to be written)
With a Java-enabled browser you can drag the points in
the diagrams and see the results of your readjustments.
More Internet resources for trigonometry are highlighted by
StudyWeb and the UTK Math Archives, and an extensive list
is available from the Math Forum:
