Answer:
D.) Quadrant 4
Step-by-step explanation:
Sin theta < 0 tells us the angle is in quadrant 3 or 4
The y component is negative
Cos theta >0 tells us the angle is in quadrant 1 or 4
The x component is positive
Therefore theta must be in quadrant 4
The solution is where the two lines meet. From the the graph, it looks like
(1, -1)

Answer:
a. The critcal points are at
b. Then, is a maximum and is a minimum
c. The absolute minimum is at and the absolute maximum is at
Step-by-step explanation:
(a)
Remember that you need to find the points where
Therefore you have to solve this equation.
From that equation you can factor out and you would get
And from that you would have , so .
And you would also have .
You can factor that equation as
Therefore .
So the critcal points are at
b.
Remember that a function has a maximum at a critical point if the second derivative at that point is negative. Since
Then, is a maximum and is a minimum
c.
The absolute minimum is at and the absolute maximum is at
