math

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)
