A. Identify the graph of the equation. Then give the angle of rotation theta.
B. Graph the conic with the rotation defined in 3A.

I already know it's a hyperbola but I don't know rotation theta or what the graph is obviously.

Are you going to post the graph?

kc_kennylau · Answer

I ain't seeing no graph :/

anonymous · Answer

Oh sorry! its $$8x ^{2}+5xy-4y^2=-2$$

ranga · Answer

Both x and y are squared and they have the opposite sign and therefore this is a hyperbola.  Not sure what drawing tools you are provided to rotate the hyperbola over a 3-D cone.

anonymous · Answer

I have no idea how to do the rotation theta thing ha

ranga · Answer

Or do they just want you to rotate the axis of the hyperbola in 2D and draw the hyperbola?

anonymous · Answer

It just says "then give the angle of rotation theta."
