To begin, let’s analyze the equation
, which gives us
. Given that
lies within the interval
, we can conclude that
is in the second or third quadrant. This implies that
for some angle
such that
. To find
, we use the Pythagorean identity:
Thus,
because cosine is negative in the second and third quadrants.
Next, let’s analyze
where
. Since
is in the interval
, this means
must be in the second quadrant, corresponding to
's negative value. Using the same Pythagorean identity, we find
:
Thus,
.
Now we can find
:
We compute
as follows:
Then we can find:
To combine these fractions, we’ll need a common denominator:
Thus, the final answer is:
