By taking the reciprocal, you are essentially tabulating velocities instead of times, so it still is easy to interpret the results (unlike logarithms or many transforms). Share Cite Improve this answer Follow answered Aug 6, 2010 at 3:47 Harvey Motulsky 21k1111 gold...
A better scenario: “Hey, I found some bacteria, waited an hour, and the lump grew from 2.3 grams to 2.32 grams. I’m going to lunch now. Figure out how much we’ll have when I’m back in 3 hours.” Let’s model this. We’ll need a logarithm to find the growth rate, and t...
Logarithms and exponents form a symbiotic relationship—basically, they “undo” each other. To put that another way, logarithms are simply an exponent in a different form. For example logax = y is the same as ay= x. Another way to think of the wordlogis that it’s a question. If you...

Working With Logarithms A logarithm is anexponent, the number to which thebase(10 unless specified otherwise) must be raised to equal theargumentof the log. For example, log10(100) is the exponent to which 10 must be raised to get 100, which is 2. Your calculator has a log function to...

Separating dy from dx in dy/dx is "against the rules" of limits, but works great with infinitesimals. You can figure out the derivative rules really quickly: Product rule: We set "df * dg" to zero when jumping out of the infinitesimal world and back to our regular number system....
From the accelerating slope, it is clear the data are becoming more and more positively skewed as we reach out into their tails. The middle and right plots show the same thing for the square roots (of the data, not of the mid-number statistics!) and the (base-10) logarithms. The ...
