In column-I various trigonometric ratios are given and in column-II their values are given match the column:
Column-I | Column-II |
(i) tan (1020º) | [A] |
(ii) cos 870º | [B] 1/ |
(iii) sin | [C] –2 |
(iv) sec 480º | [D] – |
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(i) - [D]
(ii) - [A]
(iii)- [B]
(iv)- [C]
Sol. (i) tan (1020 o ) = tan (360 o ×3 –60 o )
= – tan 60 o = – 
(ii) cos (870 o ) = cos (720 o +150 o ) = cos 150 o
= cos (180 o –30 o ) = – cos 30 o = – 
(iii) sin 
= sin 
= sin 
= 
(iv) sec (480 o ) = sec (360 o + 120º) = sec 120 o
= sec (180 o –60 o ) = – sec 60 o = –2
