Answer: OPTION D.
Step-by-step explanation:
For this exercise it is important to remember the following Trigonometric Functions:
Knowing this, we can identify that:
Therefore, the ratio 
is equivalent to this Trignometric function:
Answer:
I'm afraid I need more info. I need statistics, what other flavors there are, etc.
Step-by-step explanation:
r to the 4th power = r⁴
t to the third power = t³
r to the 4th power times t to the third power would be written as:
(r⁴)(t³)
Answer:
I don't know if this is right but I hope it helped
Step-by-step explanation:

cos(2<em>θ</em>) + sin²(<em>θ</em>) = 0
Half-angle identity:
cos(2<em>θ</em>) + (1 - cos(2<em>θ</em>))/2 = 0
Simplify:
2 cos(2<em>θ</em>) + 1 - cos(2<em>θ</em>) = 0
cos(2<em>θ</em>) = -1
Solve for <em>θ</em> :
2<em>θ</em> = arccos(-1) + 2<em>nπ</em>
2<em>θ</em> = <em>π</em> + 2<em>nπ</em>
<em>θ</em> = <em>π</em>/2 + <em>nπ</em>
where <em>n</em> is any integer.
