The square root of -1 is not a real number like -2.5, 0, or 5. Instead, it is and imaginary number, i, and i = the square root of -1. The answer is imaginary because you can never take a real number, square it, and get a negative number. However, i^2 = -1.
Two coplanar lines that never intersect are called called parallel lines.
Straight lines that never cross are called parallel lines.
Looks like all real numbers to me, but then again it could be the intersection of the imaginary numbers and the friendly numbers. You never know with this sort of thing.

The real solutions are the points at which the graph of the function crosses the x-axis. If the graph never crosses the x-axis, then the solutions are imaginary.
Asymptotes are the guidelines that a hyperbola follows. They form an X and the hyperbola always gets closer to them but never touches them. If the transverse axis of your hyperbola is horizontal, the slopes of your asymptotes are + or - b/a. If the transverse axis is vertical, the slopes are + or - a/b. The center of a hyperbola is (h,k). I don't know what the rest of your questions are, though.
Imaginary.
The difference, major or not, is that an eclipse and a hyperbola are not related, at all. You might have meant to say "Ellipse". In that case, an ellipse is a closed line shape of which the left and right bouts are symmetrical and the top and bottom bouts are also symmetrical. A hyperbola can never close, and only its left and right parts are symmetrical.
that is called the orbit. that's where they revolve.
Noughts and crosses
Nowhere. They never existed. Gryphons are myths and imaginary creatures.
he realised that marcee, the imaginary niece of his imaginary roommate never seemed to get any older
Imaginary People are "people" that are not real and the will never be real. Some younger aged children act like they have friends named bob and such!
Imaginary friend. lulz.
The unicorn is an imaginary creature, and was never born.
You will never have an imaginary number when finding the area of a circle. Never. Imaginary numbers came to be when mathematicians were upset that a negative number couldn't have a square root. You will usually find them when using the quadratic formula.
