The Trigonometer

The Trigonometer, a Living Protractor!  A device that deals with the nightmare of Trigonometry.

Are you facing the below problems?

  1. Trigonometry is hard, discrete and draining your time and effort.


  1. The trigonometric circle has a rotating radius; so, is it difficult for you to imagine rotating objects by only drawing them on papers.


  1. To draw a trigonometric circle, you need a paper, a ruler, a pencil, a bracket, a compass, and a protractor; all this mess is wasting your time.


  1. The problem of formulas: you are not able to memorize them.  Example:



  1. You are not able to grasp the issue of periodicity:



Below is the Solution!

Changing the Gravitational Constant

Imagine if you can change the Gravitational Constant.  What fun you can have!  And, it would be very useful too:


Well, a couple of years ago, the Gravitational constant seemed like it was not so constant.  A variation of G was noticed, and this variation oscillated over a 5.9 year period:

So, what can be causing this variation?  Most believe that it is not G that is changing.  Rather, this variation may be due to tidal forces and/or changes due to the circulation of the Earth’s molten core.  This is backed by seeing how the G variation correlates with the 5.9-year oscillatory period of Earth’s rotation rate.

Not everybody is in agreement, and further study is needed.  Go to the Phys.Org article to read more.
