Vedic
Astronomy & Trignometry
In
the Great Circle of Light which is 360 degrees ( the Bha Chakra-
the
Kala Chakra- the Zodiac )- the first 90 degrees are Oja Pada
(
Odd Tri Signs ) and the next 90 degrees are Yugma Pada ( Even
Tri
Signs ). There are two major Indian Planetary Models -
the
Eccentric Model and the Epicycle Model. In the Eccentric Model-
the
Mean Circle is called Manda Pratimandala- that is the circle
traversed
by the mean angular motion of the planet. In the Epicycle
Model-
the Planet is on the epicycle- known as Manda Paridhi.
The
Equation of Bhuja
The
degrees traversed by a planet is called Bhuja and the degrees
yet
to be traversed by a planet is called Koti in an Odd Sign. In
an
Even Sign-the degrees traversed by the planet is called Koti
and
the degrees yet to be traversed by a planet is called Bhuja.
In
other words- the degrees traversed by a planet is the same
=16=
in
the first 0 - 90 degrees and in the second Pada- it is 180
-
degrees traversed. In the 180-270 degrees arc-
it
is distance traversed - 180 degrees and in the 270-360 degrees arc
it
is 360 - distance traversed. This is known in Vedic Astronomy as
the
equation of Bhuja or Sine. Bhujajya is radius multiplied by modern
Sine.
This
mighty Circle of Light- Zodiac
Is
divided by four into Four Quadrant
Distance
traversed is Bhuja in Odd Sign
In
Even Sign- it is Koti called !
Bhuja
is Radius * Modern Sine
