Aryabhatta

• Field of Mathematics Suggested a formula to
  calculate areas of triangles and circles.
• First mathematician to give the table of the
  sines.
• Kuttaka Pulverise method consisted of breaking
  problems down into new problems where
  coefficients became smaller and smaller with
  every step.

  of a and b,also related to fractions.
• Gave a table of sins to calculate the values at
  intervals of 90/243 degree
• 45'
• Used a formula for sin (n1) X-sin nx Sin nx and
  sin (n-1)x
• Introduced Versine 1 (Cosine) into
  trigonometry.

Johannes Kepler1571-1630

• Interested in astronomy at an early age.
• Studied to become Lutheran Minister
• Became a professor of mathematics instead.
• Kepler's three laws of planetary motion.Which
  led directly to Newtons laws of Motion.
• Sometimes called Founder of modern optics.

  ellipses.

  solids.
• Proved theorems of geometry.

9
Johannes Kepler

• Discovered Fibonacci series, applied it to
  botany.
• Noted that the ratio of Fibonacci numbers
  converge to the Golden Mean.
• Early pioneer in calculus , embraced the idea of
  continuity.(others avoided due to the Zenos
  paradoxes.
