"seked" and "gradient"
[edit]§ Pyramid slopes says
- The seked of a pyramid is described by Richard Gillings in his book 'Mathematics in the Time of the Pharaohs' as follows:
- "The seked of a right pyramid is the inclination of any one of the four triangular faces to the horizontal plane of its base, and is measured as so many horizontal units per one vertical unit rise. It is thus a measure equivalent to our modern cotangent of the angle of slope. In general, the seked of a pyramid is a kind of fraction, given as so many palms horizontally for each cubit of vertically, where 7 palm equal one cubit. The Egyptian word 'seked' is thus related to our modern word 'gradient'."
Saying that two words are related is a matter of the form of the words; it has nothing to do with meaning. Inserting bracketed italicized comment "[in meaning, not origin]". --Thnidu (talk) 23:27, 29 June 2019 (UTC)
Intro
[edit]Could the diagram show the angle φ that's mentioned in the text?

Pyramid slopes - clarification needed
[edit]Could some clarification be provided in the named section? I'm having difficulty understanding what the quote below is describing. By 'circuit' does it mean perimeter?
"...based on a desire to ensure that the circuit of the base of the pyramids precisely equaled the circumference of a circle that would be swept out if the pyramid's height were used as a radius."
Once as someone can confirm if this is the case or not, I'll make a visual aid and add it to the article.FropFrop (talk) 12:27, 5 November 2023 (UTC)
