2. The great Indian
Mathematician/Mathemagician
“Aryabhata”

3. Born - 476 AD
Patliputra in Magadha(Patna)
Died - 550 AD
Era - Gupta era
Region - India
Main interests -
Mathematics, Astronomy
Major works - Āryabhaṭīya,
Arya-siddhanta

4. • The mathematical
contribution of the Aryabhata
covers arithmetic, algebra,
plane trigonometry, and
spherical trigonometry. It
also covers continued
fractions, quadratic
equations, sums-of-power
series, and a table of sines.
• Aryabhata correctly insisted
that the earth rotates about

5. APROXIMATE value of ‘PI’
 "Add four to 100, multiply by
eight, and then add 62,000. By
this rule the circumference of a
circle with a diameter of 20,000
can be approached." [15]
 This implies that the ratio of the
circumference to the diameter is
((4 + 100) × 8 + 62000)/20000 =
62832/20000 = 3.1416, which is
accurate to five significant
figures.

6.  In Aryabhatiya, Aryabhata provided elegant results
for the summation of series of squares and cubes
