I understand the concept and know the identities, however our teacher offered us more difficult bonus problems and this one threw me for a loop.
The problem is
the square root of (1-sin(theta))/(1+sin(theta)) = 1/(sec(thetha) - tan(theta))
My question is... can you square both sides? I tried that and worked the right side until I got (1-sin^2(theta))/(1+sin^2(theta)) ... which, if I took the square root of, I would get (1-sin(theta))/(1+sin(theta)) however I can't just take the square root of one side.
I really don't know where to go with this problem..
Any help is appreciated!
Also, sorry if it makes no sense when I wrote it out.. if you would like me to write it out as an image so it makes more sense, I can. Thanks!
