2) 90

3) 3pi/2

4) pi/2, -3pi/2

5) 90, 270

6) 0

7) pi

8) -2pi, 0, 2pi

Step-by-step explanation:

1) sinx = 0

x = 0, 180, 360

2) sinx = 1

x = 90

3) sinx = -1

x = 270 or 3pi/2

4) sinx = 1

x = pi/2, pi/2 - 2pi = -3pi/2

5) cosx = 0

x = 90, 360

6) cosx = 1

x = 0, 360

7) cosx = -1

x = pi

He mathematics department of a college has 6 male professors, 8 female professors, 14 male teaching assistants, and 7 female

irinina [24]

Total number of people in the department = 6 + 8 + 14 + 7 = 35
Total males = 6 + 14 = 20
Total female professor = 8
Total males or professor = 20 + 8 = 28

$P(\text {male or professor}) = \dfrac{28}{35} = \dfrac{4}{5}$

$\boxed {\boxed {\text {Answer: P(male or professor) = }\dfrac{4}{5} }}$
