LHS
(1/sinA - sina)(1/cosA - cosA)
= (1-sin^2A/sinA)(1-cos^2A/cosA)
= (cos^2A/sinA)(sin^2A/cosA)
= cos^2A.sin^2A/sinAcosA
= cosAsinA
RHS
convert the values of tanA and cotA in terms of sinA and cosA
= cosAsinA/sin^2A+cos^2A
= cosAsinA (bcz value of cos^2A+sin^2A=1)
LHS=RHS
HENCE PROVED
HOPE THIS HELPS WELL.
