(highly recommended)
Play
a Piano (http://www.frontiernet.net/~imaging/play_a_piano.html)
- Create, view, and listen to a sound wave. This interactive
Java applet lets you play the piano using your mouse or your
computer's keyboard. As you play the piano, you'll see the wave
forms as well as hear them. The piano can also play a song for
you, while you watch. (highly recommended)
Beats
(http://cips.colorado.edu/phys1240/Beats/) -
A Java applet that adds two sine waves together (with sound)
and lets you change the frequency on one so you can hear the
modulation. (highly recommended)
Interference
of Sinusoidal Waveforms (http://www.journey.sunysb.edu/ProjectJava/WaveInt/home.html)
- This Java applet lets you add two sine waves together...
You get to see each separately too. Frequency, amplitude, etc.
can be changed.
(highly recommended)
Function
Squashing (http://tqd.advanced.org/2647/algebra/squash.htm
) - There are cool things you can do by just messing
around with constants in equations. This site explores the things
you can do with periodic functions like sine and cosine. It
also explores translation and vertical and horizontal scaling.
Periodic
Functions (http://tqd.advanced.org/2647/algebra/ftperiod.htm
) - A really nice lesson in periodic functions with examples.
Functions
(http://www.thomson.com/pws/math/modules/topics/function/function.htm)
- An introduction to functions, and how they are used
in calculus - logarithmic, exponential and trigonometric.
Inverse
Trig Functions (http://www.acts.tinet.ie/inversetrig.functions_668.html
) - A page in the site Project Trig: Lessons and examples.
A
Short Course in Trigonometry (http://aleph0.clarku.edu/~djoyce/java/trig/
) - This is a very nice on-line course (by David Joyce
at Clarke Univ.) using JAVA to demonstrate trig. History
and scientific applications of trig are discussed too.
FAQs
About Trig (http://www.best.com/~nessus/trig/index.html)
- This site lets you use JAVA to get a great visual understanding
of trig: right triangles, amplitudes and frequencies, tangents,
etc.
Project
Trigonometry (http://www.acts.tinet.ie/trigonometry_645.html)
- A complete course in trig. Lots of explanations and
examples.
Triangles,
Circles and Waves (http://www2.ncsu.edu/unity/lockers/users/f/felder/public/kenny/papers/trig.html
) - This is a very nice site that is meant as a guide
to help you review trigonometry. It assumes you're already familiar
with the basic concepts, and just need to have things cleared
up or refreshed.
SineArt
(http://www.sineart.com) - These pages
and the images that will stimulate your retinas are dedicated
to this web designer's program called SineArt - Trig based chaos
and fractals.
Estimate
the Distance to Saturn Using Trig (http://www.amtsgym-sdbg.dk/as/AOL-SAT/SATURN.HTM
) - This site goes back to 1610, were Galileo applied
planet shadows ("phases") in order to estimate the
distance towards Venus. In this exercise, students may - applying
simple math - measure the distance to Saturn, the diameter of
the planet and its ring system and the mass of this huge gas-planet.
