Problem- csc(A-B)=secB
---------------- <<< divide bar
sinA-cosAtanB
Homework Equations
well i tried to put in terms of sin cos and I've gotten stuck
The Attempt at a Solution
i started off by disributing i.e.>> cscA-cscB=secB/sinA-cosAtanB
next i changed tan to sin/cos and canceled out cos so i was left with cscA-cscB=sec/sinA-sinB
changed csc to 1/sinA-1/sinB=sec/sinA-sinB
changed sec to 1/cos so i flipped and multiplied 1/sinA-sinB and got 1/sinA-1/sinB= 1/sincosA-sincosB and I am stuck here... help please
