Rewrite in terms of sinØ and cosØ: Code (Text): cot²Ø -------- +1 cscØ+1 Simplify: Code (Text): tan x ------------- csc x + cot x A friend of mine and I have been struggling over these type of problems for the past few hours, unable to find any logical and simple way to solve them. We have the answers already thanks to our handy answer key, but we need to know HOW to get the answers. If someone would be so kind enough as to walk us through these, that'd be great. We have a test tomorrow, and need to know quick ways to arrive at an answer while taking the final, so be accurate, heh. Thanks.
