Im trying to verify a couple trig identities
A) csc - cot = sin/1+cos
B) (1/secx + tanx) - (1/secx - tanx) = -2tanx
-----------------------
For A) I did (1/sin) - (cos/sin) then said that is 1-cos/sin. I just dont understand how I can change a minus to a plus and flip this to equal sin/1+cos
For B) I just have no idead and am looking for any advice to get started.
