Why did you label this "trig" ?

Your expression should be an equation if it is to represent either an ellipse or a hyperbola.
Should it be
....... = 1 ?

secondly, you have "bouncing exponents"
What is (x+3)^2/4^2 supposed to say?
the way you typed it, it would simplify to (x+3)

check and correct your typing.
