What are you trying to find the simplest form of?
There are no designated value for x or other information, so 5/x = 5/x
There's no equation/graph
≈1310.91
As far as restriction for x, there are none.
The answer is 53
arctan(1/x)
that's the most I can do
There's no question?
Assuming your question is when A(t) would be discontinuous, the answer is 0
