Prove These Trig Ratios - Reece - 01-24-2012
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.

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