Varahamihira (505 in Ujjain – 587) was an Indian astronomer, mathematician, and astrologer.

Varahamihira worked as one of the Navaratnas for Chandragupta Vikramaditya. His book Pancasiddhantika (or Pancha-Siddhantika, The Five Astronomical Canons) dated 575 AD gives us information about older Indian texts which are now lost. The work is a treatise on mathematical astronomy and it summarises five earlier astronomical treatises, namely the Surya, Romaka, Paulisa, Vasistha and Paitamaha siddhantas.

Varahamihira made important contributions to mathematics. He was also an astrologer,& is considered among the greatest Acharyas of modern astrology. He is the only author who has written treatises on



all the three main branches of HIndu / Vedic astrology. He has gifted us with the following treatises on astrology :

  • Brihat-Samhita
  • Brihat Jaatak - is considered as one the five main treatises on Hindu astrology on horoscopy.
  • Laghu Prashari
  • Laghu Jaatak
  • Yoga Yatra
  • Pancha-Siddhantika
  • His son Prithuyasas also contributed in the Hindu astrology; his book "Hora Saara" is one of the famous book on horoscopy.

    Some important trigonometric results attributed to Varahamihira

    sin^2\left( x \right) + cos^2\left( x \right) = 1


    sin \left( x \right) = cos\left(\frac\pi 2 - x \right)


    \frac \left(1 - cos \left(2x \right) \right)2 = sin^2x
