Question

cotA+cosecA-1/cotA-cosecA+1

Answer 1

Answer:

1+ cosA / sinA

Step-by-step explanation:

( cot A + cosec A ) - 1/ ( cotA - cosec A + 1)

( cosecA + cot A ) -( cosec^2 A -cot^ 2 A) / (cotA - cosecA + 1 )

( cosecA +cot A ) ( 1-( cosesA - cotA )) / ( cot A - cosecA + 1)

( cosecA + cotA ) ( cot A - cosecA +1 )/ ( cot A - cosecA +1)

( cosecA +cot A)

(1/ sinA + cosA / sinA )
