Step-by-step explanation:
Answer:
Step-by-step explanation:
Given is a differential equation as

Divide this by t to get in linear form

This is of the form
y' +p(t) y = Q(t)
where p(t) = 1/t
So solution would be

siubstitute y(1) = 16

Answer: Choice A

============================================================
Explanation:
Recall that
and
. The connection between tangent and cotangent is simply involving the reciprocal
From this, we can say,

In the second to last step, a pair of sine terms cancel. In the last step, a pair of cosine terms cancel.
All of this shows why
is identical to 
Therefore,
is an identity. In mathematics, an identity is when both sides are the same thing for any allowed input in the domain.
You can visually confirm that
is the same as
by graphing each function (use x instead of alpha). You should note that both curves use the exact same set of points to form them. In other words, one curve is perfectly on top of the other. I recommend making the curves different colors so you can distinguish them a bit better.
