1.) Find the exact value.
2.) Write the expression as a single trigonometric function or as a single number.
3.) find the exact value of the expression

let's first notice, the center of the hyperbola is at the origin, since the focus points are equidistantly 3 units away from the origin, that also means that the distance "c" from the center to either focus is 3.

it should also be notable that, the traverse axis for this hyperbola is vertical, or namely over the y-axis and therefore, the positive fraction will be the one with y-variable.

the traverse "a" component or distance from the center to either vertex is not 2, is more than 2, so we can safely put it at √5 ≈ 2.24.

all of them are elements inside set of real numbers since none of them appears to have complex number form.

hope this .
