Question

In the fourth quadrant the value of cosine function

• A. Increases from - ∞ to 0.
• B. Decreases from 0 to -1
• C. Increases from 0 to 1
• D. Decreases from 1 to 0

Answer 1

The correct option is C

Increases from 0 to 1

The value of cosine function at 270 degrees is 0 and at 360 degrees it"s 1.Thus as the angle moves from 270 degrees to 360 degrees i.e. in the fourth quadrant the value increases from 0 to 1.
