Answer:
, in degrees
Step-by-step explanation:
The secant of an angle is given by:
In this question:
So
In the first quadrant, the angle that has cosine of 1/2 is 60º.
The cosine is negative in the second and in the third quadrant.
The equivalent angle to 60º in the second quadrant is of 180º - 60º = 120º.
The equivalent angle to 60º in the third quadrant is of 180º + 60º = 240º
So the values of in the interval are:
, in degrees
