Multiply the equation:
The solution set is the same, because multiplying both sides of an equation by a non-zero number doesn't change the solution set. In fact, if you rewrite the equation as
Multiplying this by 3 (or whatever number, for all it matters) gives
Now, a product is zero if and only if at least one of the factor is zero. So, either 
or
Since the first is clearly impossible, the second one must be true, which is the original equation.
The period of the trig function graph is 2pi
Go from crest to crest and measure the distance and that is the length of one period or 1 cycle of the wave.
Hope this helped! Any questions please feel free to ask. Have a great day!
Answer:
From what I found, the answer is parallel
