Answer:

cosec4 0 - cosec20 = cot4 0 + cote

(i) 2 sec 0 - sec4 0 - 2 cosec2 0 + cosec4 0 = cot4 - tan4 .

1+cos - sine

(1)

= cot

(ii)

sin (1 + cos)

tan 0-1 = sec2 0 + tan 0.

tan 0-1

1 + cosec A

cos? A

sin A

(ii)

1- cos A

1 + cos A

1-sin A

cosec A

1 + cos A

(1)

1 + sin A

V1-sin A

= tan A + sec A

(ii)

1-cOS A

= cosec A - cot A.

1 + cos A

(1)

sec A-1

+

V sec A +1

sec A+1

sec A-1

= 2 cosec A

= 1 + cosec A.

(ii)

cos A cot A

1-sin A

1 + tan A 1 + cot A

+

sin A

cOS A

= 2 (sec
