Answer:

4th quadrant

Explanation:

Sec in Cartesian form is


\sec( \alpha ) = (r)/(x)

In order for sec to be positive, we must have a positive x value so we must be in Quadrant 1 or quadrant 4.

cot is negative so that menas y must be negative so.

The quadrant that has a positive x value and negative y value is 4th quadrant.
