What does x equal? In order to find the relationship between x and y we need to know both values at a given instance. For example, if x = 10 while y = 20/3, then we know that you = 20x/30 or 2x/3.
If the number ends with an even number or a number that is always divisible by 2. Or every number that ends with 5 or zero is always divisible by 5 too. Bdause for example in a fraction we do 10/5 and it will be equal to 2/1 or 2. Hope it helped you!
By definitions of the (co)tangent and cosecant function,
Turn everything into fractions with common denominators:
Recall that 
, so we can simplify both sides a bit.
On the left:
On the right:
(as long as 
, which happens in the interval 
when 
or 
)
So we have
Answer:
0
Step-by-step explanation:
Subtract 3 from 3 leaving you with -2y = 0
Divide -2 on both sides to isolate y. 0/-2 is 0.
