Web page assignment: The Moscow and Rhind Papyri. ( Place a link to this paper on your electronic journal web page for this class.)
On the Internet and/or in printed resources, find information about these papyri. Write a description (on a web page) (approximately 1 page). Include in your information for each -- when they were discovered, a picture or link to a picture of part of the contents of each papyrus on the page, an example of what is contained on the papyri, and why they are important -- plus anything else you find interesting about them.
Cite your references. Then include discussion of the following problems:
1. Problem 10 of the Moscow Papyrus computes the surface area of a hemispherical basket of diameter d = 4 + 1/2 to be (1 - 1/9)2 *(2d)*d.
Show that if we use Pi as 4*(8/9)2, the correct formula: Pi * d2 /2 results.
You can go to this link: EGYPTIAN
GEOMETRY - Mathematicians of the African Diaspora to get a line by
line translation of the problem.
Cite the source of your problem.
( To receive a better than average grade on this you must give clear and complete explanations, going beyond the minimum requirements. For the problems, start with a statement of the problem. Then give a mathematically clear and correct explanation. )
Written Homework Exercises:
B.1. Write each of the following numbers in base 60 form and then cuneiform notation.
B.2. Convert the following numbers from base 60 (sexagesimal) to decimal:
2, 31, 45
2, 12; 12
B.3. Find via search through references or the Internet suggestions of why the Babylonians might have used base 60 for their number system.
B.4. Discuss the advantages of the Babylonian number system over the Egyptian number system.
B.5. Translate the approximations in ;8, 34, 16, 59 < 1/7 < ;8,34, 18 to base 10 and then compare their accuracy to the value of 1/7.
B.6. Express the numbers in the following problem in sexagesimal notation -- then compute the division using the method of multiplying by the reciprocal (also write down the reciprocal first in sexigesimal notation. Then convert to a fraction in our notation.
a) 31 / 15
b) 49 / 12
B.7. In a manner somewhat similar to the in class exercise, solve the following Babylonian problem by getting obtaining a quadratic only in (x-y).
x + y = 50, x2 + y2 + (x-y)2 = 1400. Hint: Subtract the square of the first equation from twice the second equation, again to get a quadratic in x-y.
Web page assignment: Babylonian Geometry: Plimpton 322 TabletOn the Internet and/or in printed resources, find information about this tablet. Write a description (on a web page) (approximately 1 page). Include in your information when it was discovered, a picture or link to a picture of the tablet on the page, what is contained on the tablet, and why it is important. Cite your references. Place a link to this paper on your electronic journal web page for this class.
Exercise: Use the method indicated in the article at Mac-Tutor site: Al-Khwarizmi.on the following:
