The same principle can be applied to different situations. This java applet give you an example of such application. http://www.merlot.org/merlot/viewMaterial.htm?id=75561 A general purpose Fourier analysis/synthesis application with a graphical interface. In analysis mode, the user can select from a list of standard functions, select the truncation level for the Fourier series, and observe the amplitudes, phases, and fit of the resulting series. In synthesis mode, the user can adjust amplitudes and phases and observe the graphical result. http://www.merlot.org/merlot/viewMaterial.htm?id=89885 A site devoted to graphical presentations on many subjects, most notably physics, mathematics, and biology. Many shockwave applets available. http://www.merlot.org/merlot/viewMaterial.htm?id=77291 Challenges for Electronics is a suite of seven educational programs for electricity, electronics and math. The titles of the seven programs are Basic Circuits Challenge, DC Circuits Challenge, AC Circuits Challenge, Trigonometry Challenge, Digital Challenge, Solid State Challenge and Power Supply Challenge. Each program contains several interactive activities. Activities for both circuit analysis and troubleshooting are included. The programs grade and correct all student work immediately. Student scores can be stored on diskettes or printed. The material is suitable for use as a supplement to classroom or tutorial instruction. The programs can also be used as a refresher course for employees who have already had basic electrical or electronics training. The programs run for ten executions of any time length. After ten executions, the programs become limited capability demos. http://www.merlot.org/merlot/viewMaterial.htm?id=82992 The PADs are a set of Java applets that allow students to respond to questions on the web by drawing a diagram or making a graph. These can then be automatically evaluated and (optionally) feedback can be provided. A range of parameters allow users to change appearance, functionality and what constitutes correct. The applets and a collection of exercises are available on the website. http://www.merlot.org/merlot/viewMaterial.htm?id=84705 Print Cartesian, engineering, polar, isometric, hexagonal, probability, Smith chart and logarithmic graph paper free from your computer. http://www.merlot.org/merlot/viewMaterial.htm?id=82674 Objects are drawn in the first quadrant of body axes x,y,z. Positions are described in terms of both body angles and Euler angles. For simplicity, equal body angle rotations are made. Rotation direction cosine arrays are calculated and three two-dimensional projections are made. http://www.merlot.org/merlot/viewMaterial.htm?id=91054 This is the beginning of an online course to get to grips with 3D vectors for anyone who wants to learn. Most of the material is about UK A-level difficulty, so if you're studying a maths course involving vectors I hope working through it won't harm your grades:) Also if you're interested in related topics, such as 3D graphics programming or Newtonian mechanics, I hope you'll find something useful or interesting. http://www.merlot.org/merlot/viewMaterial.htm?id=90305 Applet shows many particles engaged in a chase to demonstrate respective motion. http://www.merlot.org/merlot/viewMaterial.htm?id=88614 A huge collection of winning physics educational software, mostly applets and downloadable executables. Covers nine consecutive years, beginning Jan. 1991.
