Retrograde Planets

• Why do planet appear to be retrograde ..ie move backwards ? while moving backwards and again moving forward they become Stationary , what is the rational behind being stationary ?
• The Bhchakra is revolving around the earth ...that is denoted by circle one [inner circle in top image ...the outer circle is the motion of planet mars ...The numbers 1.2.3.4.5.6.7 are the variable motion of the bhachakra and mars .. at given instance 1 2 3 4 5 6 ...
• as visible from EARTH
• let us project these points onto a plane [ as seen from earth ] ... at point 1 of bhachakra [zodiac] corresponding point on the track of motion of mars projects as 1 on the plane .. similarly 2 , 3 also projects linearly ... at point 4 the motion of mars differs with motion of zodiac .. the projected point is now little behind the point 3 ... so also point 5 and at point 6 is again linearly head of point of 3 ...and so also 7 is head of 6 ... this gives a feeling of backward motion and forward motion to the onlooker on earth when he fixes the position of mars wrt zodiac ...
• bhachakra point goes ahead ... say mars in aries 20deg ,, and then point 20 deg aries itself moves ahead then mars seems oving backwards becuase then mars wil be at 19 deg aries
• yes bhachakra moves at 18.5 miles /sec and mars at 15 miles per sec
• In surya sidhdhanta .. the retrograde of MARS is given as Sigrocchha - Mars = 164 deg .... that means when Mars is 164 deg from sigroccha [ usually mean position of SUN ]
• when a planet turns RUJU from VAKR gati ... it becomes stationary for a moment ... this can be seen from the image 2
• Let M be the mean position of the planet [ mean position is the point that actually revolves around the earth ...] and let P be the actual true position of PLANET . [ this point P is on a circle which is epicycle of the planet
• ruju means direct
• The radius of the epicycle is 'z' and let E point be earth ..and S be Sun
• Surya siddhant says 164 deg .. this is given to astrologers .. that is jnana .. but what vigyana behind it rationale behind this 164 deg given in SURYASIDHHANTA ... ?
• iF 'n' is the mean daily motion of the SUN , "t " be the number of the days since Sun 'S" was at the first point of ' ARIES " ................. let angle
• thus dL/dt = n - dy/dt +dx/dt
• PM = z [ radius of epicycle ] EM= r [ radius of mean motion of planets ie mars ] bith z and r are constants
• MQ = z cos y
• PQ = z siny
• EQ= EM + MQ = r + z cos y
• tan x = PQ / EQ = z sin y / (r +cosy )
• x= taninverse [ z siny /( r+ z cosy ) ]
• dx /dt = (dy/dt ) (z^2 + rz cos y )/ ( r^2 + z^2 + 2rz cos y )
• now substitute the above equation in dL/dt = n- dy/dt + dx/dt
• dL/dt = n + dy/dt [ ( z^2 +rz cos y ) / (r^2 + z^2 + 2rz cos y) ]
• If n is the daily motion of SUN and n` is the daily motion of PLANET and C is some constant ... then y = ( n-n` ) (t+C) so dy/dt =(
• substituting this is the equation dL/dt
• dL/dt = [nz^2 + n`r^2 +rz (n+n`) cos y ] / [ r^2 + z^2 + 2rz cos y ]
• when the pLANET has to become Stationary ... dL/dt = 0
• ie nz^2 + n`r^2 +rz (n+n`)cos y = 0
• so cos y = - ( nz^2 + n` r^2 ) / rz (n+n`)
• In case of MARS .. n= 0.98560265 deg and n`= 0.5240193deg , z= 233.5 deg , r =360 deg substituting these in equation .. ..........cos y = -0.9586391
• y= 180 - cosinvers [ 0.9586391 ]
• y= 163.4636 and SURYASIDHDHANTA says y= 164
• The MODER ASTRONOMY gives cos y = - [ a^1/2 ]/ [a -a ^1/2 +1 ] where a is the mean distance between sun and the planet in astronomical units .. one astronomical unit is distance between earth and sun
• for mars modern astronomy y = 163.215 ... suryasidhdhant y= 164 drik sidhdhant y= 163
• SO CAn we say VEDIC SCHOLARS were AWARE OF TRIGONOMETRY AND CALCULUS
• so science which is heavily dependent on modern mathematics can be said to be something new OR repeat telecast of AGEOLD ?
• Surya siddhanta / modern astronomy values for various planets to become retrograde . when their seeghrakendra are .. kuja =164 / 163.215 ..... budha = 144 /144.427 jupiter = 130 /125.565 venus = 163 /167.005 saturn =115/114.466
• the greter difference can be seen in jupiter and venus ...
• Vijay Jain d is derivative
• what could be the reason this knowledge of deep mathematics evaporated from continent that we read TRIGONOMETRY and calculus as something discovered by WESTERN mathematicians .. and no teacher in the school ever says yes It was KNOWN .. ?
• IS this thread a bouncer ?
• Vijay the image is two dimension and lateral projection .. kindly imagine it as above earth and projection into sky ..
• yes there is change in elongation of signs itself of zoiac at north pole

• arey abhi nahi kya maine poora equation likha isko kya means ki jarorat hai ... its maths ... ganit hai .... bhagvaan bade ganitagnya hai ...

• Publishing will not help ... madhwa bramhins should know them and take up jypotishya .. for all purpose maths is astronomy ... and useful for jyotishya ... because many bramhins left learning jyotishya and average brains became panchangakartas .... we have lost mathematics ... to such an extent that .... when europeans starting teaching as our own subject .. we thought its a great invention and something we never knew about .. THIS pitiable state of education is because ..of bramhins not keen to learn jyotishya and do manan on it /.
• the very sine is itself a series .. if you want to calculate sine or cosine , you use series
• Higher mathematics is just concepts , in schools and college conceots are never told , but one is expected to learn the formulaes .. which seems useless and unineteresting
• for example z=x+iy .... now why in the world do we require i a complex number .... most wont know
• but if we are told that these are representation of signals ..then the concept becomes inetresting and useful
• But vedic teachings do not stick to symbolism ,, it teaches concepts directly .. a vedic guru gives very secret sciences in direct manner
• all those who are good at maths , should try to find out how these answers have come ... they should solve them in their rough notes to appreciate the planetary motion
• there are may such applications .. like fiding equation of time . true positions of sun and moon .. apparent\\
• the actual terminologies in sanskrit are ... seegra , koti phala dohaphala sphutakoti ..seeghrakarna ////seeghrakarna [hypoteneuse ] = sqrroot {( sphutakoti)^2 + (Dohaphala )^2 }
• no maths no jyotish ! No jyotish no MOXA
• A modern astronomer feels a vedic astrologer does not ahve understanding of ,athematics of planetary MOTION as he sees through his telescopes ... WHAT can we say about these pseudospacescientists ......

• there will be two solutions for dL/dT=0 // y= 164 and y=360 -164 = 196 so planet becomes ruju after 196 deg ... it remains retro in between 164 and 196 ... these are degrees of seeghrakendra of mars and not longitudes of mars /... ongitude is found out by its position inepicycle an then corresponding center of epicycle ..
• epicycle is wrt to DHRUVA .. allplanets are tied to DHRUVA , the tailend of SHimshumaar ..
• yes all planets have epicycle
• how useful was this post ?
