L.H.S
(cosec@+cot@)/(cosec²@-cot²@) - 1/sin@,
(cosec@+cot@)/1 - cosec@,
cot@,
now take R.H.S
1/sin@ - (cosec@-cot@)/(cosec²@-cot²@),
cosec@ - (cosec@-cot@)/1,
cosec@-cosec@+cot@,
cot@,
then
L.H.S=R.H.S
L.H.S
(cosec@+cot@)/(cosec²@-cot²@) - 1/sin@,
(cosec@+cot@)/1 - cosec@,
cot@,
now take R.H.S
1/sin@ - (cosec@-cot@)/(cosec²@-cot²@),
cosec@ - (cosec@-cot@)/1,
cosec@-cosec@+cot@,
cot@,
