Math Analysis: (csc x - cot x)(sec x +1)

i did but at the back of my book it says that the answer is tan x :\

Well, that just means to change everything back into sine and cosine and tangent, and then simplify

could you do the steps for me please? :| I tried so many times and I still didn't get the answer from the back of the book..

nvm i figured it out myself but thx for the help anyways :p

I always change sec to 1/cos csc to 1/sin cot to cos/sin and hope for the best! in this case, (csc -cot) = (1/sin - cos/sin) = (1-cos)/sin (sec+1)= (1/cos +1) = (cos+1)/cos when you multiply them you get (1-cos^2)/(sin cos) you should know 1-cos^2 = sin^2 so it looks like you get sin^2/(sin cos) = sin/cos = tan

thx but I already solved it xP you came to late.. :p

that was for anyone who wondered how to do it. You could have posted your answer, 'cause some people might want to know how to do it.

oh, well thx haha :) I'll remember that next time xP Thx for your time and effort~ ^^
