yeah dont fail
locus of 2 points formula
perpendicular slope of the slope between the 2 points
circle formula
(x-h)²+(y-k)²=r² also same as locus of one point
parabola opening right/left
4p(x-h)=(y-k)² p = dist between vertex+focus point p<0 is down
parabola opening up/down
4p(y-k)=(x-h)² p = dist between vertex+focus point p<0 is left
ellipse general formula
(x-h)²/a² + (y-k)²/b² = 1
a>b
ellipse solve for c
c²=a²-b²
e=????
c/a
hyperbola formula : transverse axis is horizontal
(x-h)²/a² - (y-k)²/b² = 1
a - distance from center to vertex
c - distance from center to focus
hyperbola formula : transverse axis is vertical
(y-k)²/a² - (x-h)²/b² = 1
a - distance from center to vertex
c - distance from center to focus
hyperbola solve for c
c² = a²+b²
angle of rotation of conics
cot(2 theta) = (A-C)/B
rotation of conics x=???
x= x’cos(theta) - y’sin(theta
rotation of conics y=???
y= y’cos(theta) + x’sin(theta)
tan = ???
sin/cos aka y/x
eliminate parameter =???
remove t by substitution
rectangular to polar: (x,y) =???
(rcos(theta),rsin(theta))
polar to rectangular: (r, theta) =???
(sqrt(x²+y²), tan^-1(y/x)) look for domain issues
sin+cos graph is???
oui know this stuff or fail
trig table
u should know this if not study it and know it or fail
famous curves(polar stuffs)
yeah know this
symettry tests for polar curves
partial fraction denominators are???
this is literally ch 7 dont fail on this
matric multiplication
only when inner dimenions ==
determinant of 2×2 matrix formula???
cramers rule???
cyrptography (prob not on test but whtvr)
