The ellipse, hyperbola and parabola Flashcards
1
Q
What is the equation of an ellipse
A
X^2 ÷ a^2 + y^2 ÷ b^2 = 1
2
Q
What are the intercept of an ellipse with the equation in its proper form
A
(+-a, 0), (0, +-b)
3
Q
What is the equation of a hyperbola
A
X^2 ÷ A^2 - Y^2 ÷ B^2 = 1
4
Q
Properties of a hyperbola
A
Symmetrical at x and y axis
X intercept when y=0 (+-a, 0)
5
Q
What are the asymototes of a hyperbola in it’s proper form
A
Y= +- b/a
6
Q
Special case of a hyperbola
A
Xy = c^2
Verticies (C, C) and (-c, C)
Coordinate axis as asymptotes
