Does adjusting the formatting of a table require citing sources???
A table in this article looked like this:
 * $$\sin \frac{\pi}{10} = \sin 18^\circ = \frac{\sqrt 5 - 1}{4}=\frac{\varphi-1}{2}=\frac{1}{2\varphi}$$


 * $$\cos \frac{\pi}{10} = \cos 18^\circ = \frac{\sqrt{2(5 + \sqrt 5)}}{4} $$
 * $$\tan \frac{\pi}{10} = \tan 18^\circ = \frac{\sqrt{5(5 - 2 \sqrt 5)}}{5} $$
 * $$\cot \frac{\pi}{10} = \cot 18^\circ = \sqrt{5 + 2 \sqrt 5} $$
 * $$\sin \frac{\pi}{5} = \sin 36^\circ = \frac{\sqrt{2(5 - \sqrt 5)} }{4}$$
 * $$\cos \frac{\pi}{5} = \cos 36^\circ = \frac{\sqrt 5+1}{4} = \frac{\varphi}{2}$$
 * $$\tan \frac{\pi}{5} = \tan 36^\circ = \sqrt{5 - 2\sqrt 5} $$
 * $$\cot \frac{\pi}{5} = \cot 36^\circ = \frac{ \sqrt{5(5 + 2\sqrt 5)}}{5} $$
 * $$\cos \frac{\pi}{5} = \cos 36^\circ = \frac{\sqrt 5+1}{4} = \frac{\varphi}{2}$$
 * $$\tan \frac{\pi}{5} = \tan 36^\circ = \sqrt{5 - 2\sqrt 5} $$
 * $$\cot \frac{\pi}{5} = \cot 36^\circ = \frac{ \sqrt{5(5 + 2\sqrt 5)}}{5} $$
 * $$\tan \frac{\pi}{5} = \tan 36^\circ = \sqrt{5 - 2\sqrt 5} $$
 * $$\cot \frac{\pi}{5} = \cot 36^\circ = \frac{ \sqrt{5(5 + 2\sqrt 5)}}{5} $$
 * $$\cot \frac{\pi}{5} = \cot 36^\circ = \frac{ \sqrt{5(5 + 2\sqrt 5)}}{5} $$

I changed it so that it looked like this:

\begin{align} \sin \frac{\pi}{10} & = \sin 18^\circ = \frac{\sqrt 5 - 1}{4}=\frac{\varphi-1}{2}=\frac{1}{2\varphi} \\[5pt] \cos \frac{\pi}{10} & = \cos 18^\circ = \frac{\sqrt{2(5 + \sqrt 5)}}{4} \\[5pt] \tan \frac{\pi}{10} & = \tan 18^\circ = \frac{\sqrt{5(5 - 2 \sqrt 5)}}{5} \\[5pt] \cot \frac{\pi}{10} & = \cot 18^\circ = \sqrt{5 + 2 \sqrt 5} \\[5pt] \sin \frac{\pi}{5} & = \sin 36^\circ = \frac{\sqrt{2(5 - \sqrt 5)} }{4} \\[5pt] \cos \frac{\pi}{5} & = \cos 36^\circ = \frac{\sqrt 5+1}{4} = \frac{\varphi}{2} \\[5pt] \tan \frac{\pi}{5} & = \tan 36^\circ = \sqrt{5 - 2\sqrt 5} \\[5pt] \cot \frac{\pi}{5} & = \cot 36^\circ = \frac{ \sqrt{5(5 + 2\sqrt 5)}}{5} \end{align} $$ This did not alter the information in the table but made the formatting neater. Notice that the leftmost the column of "equals" signs is now vertically aligned and there's a bit more space between lines. But User:Epinoia reverted it with this summary:"you might be right, but you will have to cite sources to support a change like this" Is there any sort of source that could be cited for something like this?

 * My apologies if I misread your edit - it appeared as if you were changing the math, not just the formatting - if I am mistaken please re-instate your edit - cheers - Epinoia (talk) 01:47, 6 January 2019 (UTC)
 * Done. &mdash; Cheers, Steelpillow (Talk) 10:33, 6 January 2019 (UTC)
