Hope this helps. Have a great day, you amazing bean child.
(Yes you are now my bean child. Get over it)
If interpreted as shown, the order is shown in the lines following
1+sin(x)/1-sin(x)-1-sin(x)/1+sin(x)
=1 + ((sin(x))/1) - sin(x) -1 - (sin(x)/1) + sin(x)
which is completely meaningless for the purpose of this question.
The left-hand side is
![\frac{1+sin(x)}{1-sin(x)}-\frac{1-sin(x)}{1+sin(x)}](https://tex.z-dn.net/?f=%5Cfrac%7B%3Cspan%3E1%2Bsin%28x%29%7D%7B1-sin%28x%29%7D-%5Cfrac%7B1-sin%28x%29%7D%7B1%2Bsin%28x%29%7D)
common denominator is (1-sin(x))(1+sin(x)), so
![=\frac{(1+sin(x))(1+sin(x)-(1-sin(x))(1-sin(x))}{(1+sin(x)(1-sin(x)}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B%281%2Bsin%28x%29%29%281%2Bsin%28x%29-%281-sin%28x%29%29%281-sin%28x%29%29%7D%7B%281%2Bsin%28x%29%281-sin%28x%29%7D)
![=\frac{(1+sin(x))^2-(1-sin(x))^2}{(1+sin(x)(1-sin(x)}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B%281%2Bsin%28x%29%29%5E2-%281-sin%28x%29%29%5E2%7D%7B%281%2Bsin%28x%29%281-sin%28x%29%7D)
![=\frac{(1+1)(2sin(x))}{(1-sin^2(x)}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B%281%2B1%29%282sin%28x%29%29%7D%7B%281-sin%5E2%28x%29%7D)
using a^2-b^2=(a+b)(a-b)
![=\frac{4sin(x)}{cos^2(x)}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B4sin%28x%29%7D%7Bcos%5E2%28x%29%7D)
![=\frac{4tan(x)}{cos(x)}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B4tan%28x%29%7D%7Bcos%28x%29%7D)
![=4tan(x)sec(x)](https://tex.z-dn.net/?f=%3D4tan%28x%29sec%28x%29)
