divide numerator and denominator by sinA
and we get
put the value of 1
cotA+cosecA-(cosec²A-cot²A)/ cotA -cosecA + 1
=> cotA+cosecA-(cosecA-cotA)(cosecA+cotA/cotA-cosecA+1
taking cotA+cosec A as common
=>(cotA+cosecA)(cotA-cosecA+1)/(cotA-cosecA+1
=>cotA+cosecA
and we get
put the value of 1
cotA+cosecA-(cosec²A-cot²A)/ cotA -cosecA + 1
=> cotA+cosecA-(cosecA-cotA)(cosecA+cotA/cotA-cosecA+1
taking cotA+cosec A as common
=>(cotA+cosecA)(cotA-cosecA+1)/(cotA-cosecA+1
=>cotA+cosecA
