Short Answer: pi/6 5pi/6 pi/2 3pi/2
Step One

Pull cos(theta) our of the brackets
cos(theta)*(sin(theta) - 1/2) = 0         Do not divide by cos(theta)

Step Two
Identify the sources of the solution
.
You have 2 sources of solutions for this
The first is cos(theta)

<u>source 1</u>
cos(theta) = 0 
Theta can have 2 values 
pi/2 and (3/2 pi)

<u>Source 2</u>
You also have another source
sin(theta - 1/ 2 = 0
sin(theta) = 1/2
Theta can have 2 values One in quadrant 1 and one in quadrant 2

<em>Quadrant 1</em>
Theta = 30o = 30/180 * pi = pi/6

<em>Quadrant 2</em>
Theta = 180 - 30 = 150o = 150o/180 * pi = (5/6) pi

Lee works at a job where her pay varies directly with the number of hours she works. Her pay for 6.5 hours is 49.40. Write a dir
puteri [66]
X = pay and y = hours worked
direct variation equations are of the form:
dependent variable = k(independent variable)
we need to find k, the constant of variation
x = ky
49.40 = 6.5k
7.6 = k
EQUATION: x = 7.6y
PAY for 25 hours: x = 7.6(25) = 190 or $190
