P.T 1/(CosecA-CotA )-1/SinA=1/SinA-1/(CosecA+CotA )

Answer:
LHS = 1/(cosecA - cotA) - cosecA
= {(cosecA + cotA)/cosecA - cot} - cosecA

we know that cosecA - cotA = 1

= cosecA + cotA - cosecA

= cosecA - (cosecA - cotA)

= cosecA - (cosecA - cotA)(cosecA + cotA)/(cosecA + cotA)

= cosecA -(cosecA - cotA)/(cosecA + cotA)

= 1/sinA - 1/(cosecA + cotA)  
= RHS
