1. List in radians, the values for the lower and upper angle
boundaries of third quadrant angles.: π and 3π/2
2. An angle of 136° would fall in
the quadrant.: second
3. Write in radians one angle that is a quadrantal angle.: π other possibilities:
0, π/2, 3π/2, 2π, etc.
4. When in standard position, the vertex of an angle falls on the:
origin
5. An angle of 11π/6 would
fall in the quadrant?: fourth
6. The ending side of
an angle is called the side.: terminal
7. When in standard position, the initial side of an angle falls on the
.: positive x-axis
8. DEGREES/RADIANS: Convert each angle to the opposite measure.
(show your work)
210° and 3π/4:
9. EXACT VALUES: Find he exact value for each problem: (show
your work) cos 3π/4
tan 270°
sec 300°
cos a = -1/2, csc a > 0, find cot a
In stand position, one side of angle β passes through the point (2, -
5); find sec β
From the previous problem, find sin β.:
10. ANGLE REDUCTION: Reduce to the same function of a positive
acute angle. (show your work)
