Answer:
y = -2.5
Step-by-step explanation:
For such a problem as this, you can replace all sine or cosine functions with their midline value of 0. Then you have ...
f(x) = 0 -2.5
which simplifies to ...
f(x) = -2.5
You can leave the equation like this, or write it as ...
y = -2.5
_____
Perhaps you can see that the midline is the value of any constant added to a sine or cosine function.

Answer:
I think that what you are trying to show is: If 
is irrational and 
is rational, then 
is rational. If so, a proof can be as follows:
Step-by-step explanation:
Suppose that is a rational number. Then and can be written as follows
Hence we have that
Then
This is a contradiction because we assumed that is an irrational number.
Then must be an irrational number.
