Subject: Re: doubt in trignometry



Trigonometry is the study of the triangle.  The word means triangle
measurement.  Trig becomes important in the design of bridges,
buildings because triangles are fixed by the length of the three
sides.  A triangle will not change shape under normal conditions
because three sides of a particular length guarantees the shape of the
triangle.  It is this property that makes the triangle a strength
feature of almost all construction.  Almost any thing of strength will
have triangles as part of their construction. 

The study of triangle relationships is used in electrical engineering
as well.  The position of antennas, turrets and other devices can be
relayed to other stations by the means of snychros.  This is all based
upon trigonometry relationships.

Anything that rotates requires trigonometry to completely understand
what is happening.   This includes motors, generators and other
devices.  Trigonometry is an integral part of geometry, calculus and
other subjects in mathematics.
