ANSWER :

[cosecA- sinA][secA-cosA][tanA+cotA]

[cosecA-sinA][secA-cosA]

cosecA.secA-sinA.secA-cosecA.cosA+sinA.cosA

1/sinA.cosA - sinA/cosA - cosA/sinA +sinA.cosA

1-sin^2A-cos^2A+sin^2A.cos^2A/sinA.cosA

here 1- sin^2a = cos^2A

sin^2A.cos^2A/sinA.cosA

sinA.cosA

then

sinA.cosA[tanA+cotA]

sinA.cosA.sinA/cosA +sinA.cosA.cosA/sinA

sin^2A+cos^2A
