00:0100:01, 11 February 2022 diff hist −21 Velocity-addition formula →Properties: While the prior statement was true, it is not what is meant by being non-linear. For example, for real numbers x and y, ax by ≠ ab (x y). For a function of two 3-vectors to one 3-vector such as being discussed, linearity would normally refer to the behavior under the same scaling of each domain variable. Tag: Reverted

17:0217:02, 6 January 2020 diff hist 96 Altered chord →Alt chord: I changed the example of the problem with leaving the "G7 alt" open to interpretation. First of all, no musician worth his or her salt would even include a natural 13 in an alt chord. It is not even in the alt scale. I was startled to read this, and went on to verify it with 3 other practicing musicians, one who has taught jazz theory for 5 decades. Secondly a more common pair of interpretations would be those I have given in the changed text.

17:0717:07, 9 July 2015 diff hist 181 Probit Anyone with even modest mathematical training will want to know that the probit is the inverse of the standard normal CDF, so this should be first. That alone is likely all many readers will need to know.

20:3220:32, 31 July 2014 diff hist 724 Talk:Critical band Wondering if a cited value is correct, as implications are apparently nonsensical. Suggesting rechecking the value or explaining why it isn't as crazy as it appears.

22:2122:21, 1 May 2014 diff hist −3 m Natural logarithm of 2 The previous value was wrong in the last place if interpreted as an approximate 11=place value. I removed the trailing ellipses, as that implies the rest of the value which would be exact.

17:2517:25, 24 March 2014 diff hist 86 M/M/c queue →Number of customers in the system: The meaning of the "pi" quantity was undefined. It may be somewhat standard, but the link to defining a "probability mass function" does not use a pi notation.

18:4518:45, 11 November 2011 diff hist 99 Price elasticity of demand →Effect on total revenue: I felt an equation would help relate this section to the previous sections and be a useful presence as the visitor reads through the following paragraphs.
18:3318:33, 11 November 2011 diff hist 232 Price elasticity of demand →Effect on total revenue: As it was, this first sentence of paragraph 2 was only true for the inelastic case, and the statement about percentages is mathematically incorrect, the "approximately" is needed.
18:1418:14, 11 November 2011 diff hist 86 Price elasticity of demand →Effect on total revenue: The "price effect," I added the the qualifiers "for inelastic goods". Otherwise it directly contradicts the later statement "when the price is raised, the total revenue falls" for the elastic case.
