So I have the following hyperbola

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

I need to find the focus points of this hyperbola. What is some analytical way to do this ?

Thank yoU!

Use a double $ on this site for LaTeX

$$\frac{x^{'2}}{4}-\frac{y^{'2}}{4}=-1$$

In future posts, you need to show more of an effort than you did here. If you don't, you will get infraction points.

x^2/4 - y^2/4 = -1
Or equivalently, ##\frac{y^2}{4} - \frac{x^2}{4} = 1##.
This is a form that is simpler to work with.
