We can write x<4 in interval notation as (-∞,4) and x>5 as (5,∞).
The "or" represents the union of the two intervals.
Therefore the solution to the given inequality in interval notation is:
The third choice is the correct answer.
Solution:
Given:
Using the trigonometric ratio of cosine,
Therefore, OPTION A is correct.
