	Circle	Ellipse	Parabola	Hyperbola
Equation (horiz. vertex):	x² + y² = r²	x² / a² + y² / b² = 1	4px = y²	x² / a² - y² / b² = 1
Equations of Asymptotes:				y = ± (b/a)x
Equation (vert. vertex):	x² + y² = r²	y² / a² + x² / b² = 1	4py = x²	y² / a² - x² / b² = 1
Equations of Asymptotes:				x = ± (b/a)y
Variables:	r = circle radius	a = major radius (= 1/2 length major axis) b = minor radius (= 1/2 length minor axis) c = distance center to focus	p = distance from vertex to focus (or directrix)	a = 1/2 length major axis b = 1/2 length minor axis c = distance center to focus
Eccentricity:	0	c/a	1	c/a
Relation to Focus:	p = 0	a² - b² = c²	p = p	a² + b² = c²
Definition: is the locus of all points which meet the condition...	distance to the origin is constant	sum of distances to each focus is constant	distance to focus = distance to directrix	difference between distances to each foci is constant

some thing specially for goiitians! try printing it and pasting in ur room! i promise u wont evr forget these basic formulas which sometimes tend to slip from our minds!
