Key Concepts & Vocabulary
TermDefinitionExample
General Form of a Conic SectionThe equation Ax² + Cy² + Dx + Ey + F = 0, where A, C, D, E, and F are constants. For a hyperbola, the coefficients A and C must have opposite signs (one positive, one negative).9x² - 16y² - 36x - 32y - 124 = 0 is the general form of a hyperbola because the x² coefficient (9) is positive and the y² coefficient (-16) is negative.
Standard Form (Horizontal)The form \frac{(x-h)²}{a²} - \frac{(y-k)²}{b²} = 1. This represents a hyperbola that opens left and right, with a horizontal transverse axis.\frac{(x-2)²}{9} - \frac{(y+1)²}{16} = 1
Standard Form (Vertical)The form \frac{(y-k)²}{a²} - \frac{(x-h)²}{b²} = 1. This represents a hyperbola that opens up and down, with a vertical transverse axis.\frac{(y-3)²}{25} - \frac{(x-1)²}{4} = 1

Core Formulas
Converting from General to Standard Form
The method of 'Completing the Square'. For a term like z² + bz, add (b/2)² to create a perfect square trinomial: z² + bz + (b/2)² = (z + b/2)².
This is the fundamental algebraic process used to transform the general form equation. You must group x-terms and y-terms, factor out leading coefficients, complete the square for both variables, and balance the equation before dividing to make the right side equal to 1.
Hyperbola Foci Relationship
c² = a² + b²
Use this formula to find the distance 'c' from the center to each focus. Remember that for a hyperbola, 'a²' is always the denominator of the positive term in the standard form equation.
Asymptote Equations
For a horizontal hyperbola: y - k = ±\frac{b...
