- 18:5318:53, 16 June 2020 diff hist +287 List of periodic functions →Non-smooth functions: Added a formula and Fourier series for the Pulse Wave, as well as made the formula for the cycloid more consistent with the standards set above. Tag: Visual edit

- 18:2118:21, 16 June 2020 diff hist +53 List of periodic functions →Non-smooth functions: The Square Wave was missing its Fourier Series, The Sawtooth Wave had the wrong Fourier Series, and the Triangle Wave's Fourier Series confused two variables i and n, and had incorrect bounds for its summation. I also forgot to mention in the section on Cycloids that r was the radius of the circle. Tag: Visual edit
- 17:5817:58, 16 June 2020 diff hist +126 List of periodic functions →Non-smooth functions: I edited the formula for cycloid to yield a closed form expression given the inverse of another function. Please note that some viewers might assume f(x) is an official mathematical function f(x)=x-sin(x), so if there's anything future editors could do to make it clear that that is not the case, that'd be great!

- 19:5119:51, 4 April 2020 diff hist +56 Indefinite sum I corrected the formula so that the sum is subtracted and not added. I should note that this correction was made because, after trying it out myself, the formula gives the wrong answer when the sum is added, but gives the right answer when the sum is subtracted. While this might be considered original research, I'm afraid I had no choice, as the only link provided was explaining what the Cauchy numbers were, not where this formula came from. All I knew was that, as is, the formula didn't work. Tag: Visual edit

Also, I’m not even going to try to understand what’s going on with tan(ax) for now. Tags: Mobile edit Mobile web edit
- 19:3919:39, 18 October 2019 diff hist −2 Indefinite sum →Antidifferences of trigonometric functions: I removed some unnecessary spaces in the formulas. Also, I accidentally hit publish before writing the summary in my last edit, so I’ll give it here. In my last edit, I shortened the formulas for the sum of cos(ax), both for simplicity and for cohesion, as it is now in a format similar to that for sin(ax). I also changed an incorrect ___domain restriction. Before, the formulas implied that they were only accurate if a wasn’t an integer multiple... Tags: Mobile edit Mobile web edit

Seeing as how many other Wikipedia pages involving celestial objects contain such valse in both AU and km, I’ve decided to not make this one an exception. Note: the conversion is not cited, it was calculated by multiplying by the ratio between AU and km and using 4 sig figs from the result. Tags: Mobile edit Mobile web edit

It would be easy for the reader to assume that the variable “a” assumes the value of the length of a section of the chain whose mass, as opposed to its weight on earth caused by the force of gravity, is equal to the tension at c.

I had assumed that either it was the ending to a sentence and was followed by an uncapitalized incomplete sentence, or, far more likely, that the sentence was being interrupted by an unnecessary period.
