A table (based on 100) that demonstrates the idea.How would one use Napier's Tables:
Example: The rule of 3.Napier's logarithm tables.
Suppose a/b = c/d.
Given any three of these values, find the fourth.Napier's Theorem: If a/b=c/d then
NOG(a) NOG(b) = NOG(c)NOG(d)
Making Napier logarithm tables. (MS Excel)
How do Napier logarithms compare with modern logarithms?
The End
