Verify that each equation is an identity- directions

Problem- csc(A-B)=secB

---------------- <<< divide bar

sinA-cosAtanB

2. Relevant equations

well i tried to put in terms of sin cos and i've gotten stuck

3. 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 cancelled 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 im stuck here..... help please
