## sakigirl Group Title What conic does the equation y^2-x^2=4 represent? one year ago one year ago

1. DLS Group Title

Hyperbola.

2. sakigirl Group Title

@DLS How do you know?

3. sakigirl Group Title

I thought it would have been a circle

4. DLS Group Title

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

5. DLS Group Title

This is the general form of equation for a hyperbola.. For circle it is,(x-a)^2+(y-a)^2=1

6. sakigirl Group Title

So in order to find what it is, you divide the sides by the 4? @DLS

7. DLS Group Title

Yes,here.

8. sakigirl Group Title

Is that how you find out which conics is which? Simply divide what is whatever the number is to both sides?

@DLS

10. DLS Group Title

Depends.

You have to observe and have an idea about all the conics.
