Use a double $ on this site for LaTeXastrololo said:Homework Statement
So I have the following hyperbola
$$\frac{x^{'2}}{4}-\frac{y^{'2}}{4}=-1$$
I need to find the focus points of this hyperbola. What is some analytical way to do this ?
Thank yoU!

Oh thank you for telling me !SammyS said:Use a double $ on this site for LaTeX

Or equivalently, ##\frac{y^2}{4} - \frac{x^2}{4} = 1##.astrololo said:Homework Statement

x^2/4 - y^2/4 = -1

A hyperbola is a type of curve that is created when a plane intersects with a double cone at an angle. It is a conic section, along with circles, ellipses, and parabolas.
A hyperbola has two focus points, which are located on the transverse axis. These points are equidistant from the center of the hyperbola and play an important role in its shape and properties.
The focus points of a hyperbola can be found by using the equation (x-h)^2/a^2 - (y-k)^2/b^2 = 1, where (h,k) is the center of the hyperbola and a and b are the lengths of the transverse and conjugate axes, respectively. The focus points are located at (h ± c, k), where c = √(a^2 + b^2).
The focus points are important because they determine the shape and orientation of the hyperbola. They also play a role in defining the directrix, which is a line that is perpendicular to the transverse axis and passes through the focus points. The directrix is used to construct the hyperbola and is an essential part of its definition.
Yes, the focus points of a hyperbola can be located outside of the curve. This occurs when the hyperbola is a rotated or translated form of the standard equation (x-h)^2/a^2 - (y-k)^2/b^2 = 1. In this case, the focus points will still be located at (h ± c, k), but the center and axes of the hyperbola will be shifted accordingly.
