(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

[tex]\frac{secx-cscx}{secx+cscx}=\frac{tanx-1}{tanx+1}[/tex]

[tex]\frac{(tan^{2}x - cot^{2}x)}{(tanx + cotx)}= (tanx - cotx)[/tex]

[tex]tan^{2}2x+sin^{2}2x+cos^{2}2x=sec^{2}2x[/tex]

[tex]cot^{2}2x+cos^{2}2x+sin^{2}2x=csc^{2}2x[/tex]

3. The attempt at a solution

I've tried many times in my notebook and i'm posting these on hear as a last resort. Could someone please explain how these are done as my teacher LACKS the ability to teach.
