Prove These Trig Ratios

[Reece]

1. (Sec x / Sin x) - (Sin x / Cos x) = Cot x

2 (Cos x / Sec x - 1) + (Cos x / Sec x - 1) = 2Cot ^ 2 x
^2 means squared

3. (Sin x + Cos x) (Tan x + Cot x) = Sec x + Csc x

I can't figure these three out.
Please help. Obviously, show work. Lol.

[Listen]

Doing these right now! Will update with pics in like 10 mins buddy

Hmm, don't know much about this sorry, but I am pretty sure this should be in the Math section.
