tan220-sin220/tan220sin220
divide and multiply by tan220
=1-cos220/sin220      ( sin220/tan220 = cos220 )
=sin220/sin220
=1

tan2 20o -sin2 20o/tan2 20o.sin2 20o
=tan2 20o/tan2 20o.sin2 20o – sin2 20o/tan2 20o.sin2 20o
=1/sin2 20o – 1/tan2 20o
=cosec220o – cot220o
=1                                           [Since,cosec2x– cot2x=1]

(tan^220-sin^220)/tan^220sin^220
= (1-cos^220)/sin^220
= sin^220/sin^220
= 1
Hope it helps!
