Consider the following: 1. ( 6 ) 2. ( 3 4 ) 3. ( 5 4 ) 4. ( 2 3 )
Options
- A1 < 4 < 2 < 3
- B4 < 2 < 1 < 3
- C4 < 2 < 3 < 1
- D1 < 4 < 3 < 2
Correct answer
B. 4 < 2 < 1 < 3
Step-by-step solution
From trigonometric values 1. ( 6 )= 1 3 2. ( 3 4 )= ( - 4 )= ( 4 )=-1 3. ( 5 4 )= ( + 4 )= ( 4 )=1 4. ( 2 3 )= ( - 3 )= ( 3 )=- 3 Hence, correct ascending order is 4 2 1 3 .
