# Finding the focus points of a hyperbola

## Homework Statement

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!

I don't know...

Use a double $on this site for LaTeX $$\frac{x^{'2}}{4}-\frac{y^{'2}}{4}=-1$$ Use a double$ on this site for LaTeX

$$\frac{x^{'2}}{4}-\frac{y^{'2}}{4}=-1$$
Oh thank you for telling me !

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

So I have the following hyperbola

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.
