Question

Use traces to identify the shape
x^2-y^2+z^2=1

Answer 1

So I know about plugging k or 0 in to try and identify each plane, but I get weird equations on this one and can't identify the shape

Answer 2

@zepdrix :)

Answer 3

yz plane, x=k is x^2-y^2=1-k^2

Answer 4

or putting x=0, z^2-y^2=1

Answer 5

which would be a hyperbola, correct?

Answer 6

similarily
z=0, gives us x^2-y^2=1 which is another hyperbola
y=0, x^2+z^2=1 is a circle

Answer 7

hahah well something like this, only less potato-y!
