SOLUTION :
Given :
tan45° / cosec 30° + sec 60° / cot 45° - 5 sin 90° / 2 cos 0°
= ½ + 2/1 – 5(1)/2(1)
[tan 45° = 1, cosec 30° = sec 60°= 2, cot 45° = 1, sin 90° = 1 , cos 0°= 1]
= ½ + 2/1 - 5/2
=( ½ - 5/2) + 2/1
[By rearranging the terms]
= (1 - 5)/2 + 2/1
= - 4/2 +2
= -2 + 2 = 0
tan45° / cosec 30° + sec 60° / cot 45° - 5 sin 90° / 2 cos 0° = 0
Hence, tan45° / cosec 30° + sec 60° / cot 45° - 5 sin 90° / 2 cos 0° = 0
