Answer 2

Answer:

cosecant a+cota=k ______1

coseca-cota=1/k_________2

by 1and2

by adding them

cosecant a+cota=k

coseca-cota=1/k

_______________

2coseca =k+1/k

coseca=k^+1/2k_______4

by substrating them we get

cota=k^-1/2k___________3

dividig4/3 = cota=k^-1/2k/coseca=k^+1/2k

Cosa=k^-1/k^+1 is answer
