Nifty Practice Problems Write an equation for the given hyperbola. The hyperbola opens up-down: (2, –2) Plug in the point (2, –2): Equation:
Definition:Eccentricity of a Hyperbola The eccentricity of a hyperbola is where a is the semitransverse axis, b is the semiconjugate axis, and c is the distance from the center to either focus. Eccentricity of a hyperbola is always greater than 1!!!
Nifty Practice Problems Find an equation in standard form for the hyperbola with center at (0, 0), a = 4, e = 3/2, and a vertical focal axis. Start with a diagram? What’s the general equation? How about h and k? Now, how do we find a and b?
Nifty Practice Problems Find an equation in standard form for the hyperbola with center at (0, 0), a = 4, e = 3/2, and a vertical focal axis. The specific equation:
Nifty Practice Problems Find an equation in standard form for the hyperbola with center at (1, –4), c = 6, e = 2, and a horizontal focal axis.
