MAT336: History of Mathematics

Spring 2026

Study Guide: Quiz 10 - Lecture 2

India

Note: This is a study guide. The quiz will consist of three or four questions covering the material below. If you understand the ideas and facts in the non-computational questions and can work through the computational problems, you will be well prepared.

Note on review questions: This quiz will also include one or two questions drawn from earlier in the course (Quizzes 1–3). The review questions are listed at the end of this study guide.

Part 1: India

  1. Place the following in rough chronological order, giving approximate centuries and a one-sentence description of each: the Indus/Harappan civilization, the Śulba Sūtras, Aryabhata, the Bakhshali manuscript, and the Gwalior temple inscription.
  2. Give a one-sentence description of the Indus (Harappan) civilization. Then state two pieces of archaeological evidence that support your description of it as an organized urban civilization.
  3. Why are the Śulba Sūtras historically important for mathematics, and what kind of mathematical presentation do they use?
  4. State, in words and in the style of the Śulba Sūtras, the rule about the diagonal of a square. Then restate it in precise modern mathematical language.
  5. State, in words and in the style of the Śulba Sūtras, the rule about the diagonal of a rectangle. Then restate it in precise modern mathematical language.
  6. What is a radian? Give a definition in your own words.
  7. Indian astronomers used a circle of radius R = 3438. Explain where this number comes from.
  8. Greek astronomers tabulated chords; Indian mathematicians worked with half-chords (jya). What is the geometric relationship between a chord and the corresponding jya? Why is the jya easier to work with?
  9. What is the Bakhshali manuscript? Give its approximate date according to the most recent Oxford radiocarbon dating. Why is it important in the history of mathematics? Give two reasons.
  10. What is the difference between zero as a placeholder and zero as a number? Give one example of each.
  11. The Gwalior temple inscription is sometimes described as the oldest definitively dated zero in India. What is its date, and what number does it record? What makes it significant?
