1
New cards

locus of 2 points formula

perpendicular slope of the slope between the 2 points

2
New cards

circle formula

(x-h)²+(y-k)²=r² also same as locus of one point

3
New cards

parabola opening right/left

4p(x-h)=(y-k)² p = dist between vertex+focus point p<0 is down

4
New cards

parabola opening up/down

4p(y-k)=(x-h)² p = dist between vertex+focus point p<0 is left

5
New cards

ellipse general formula

(x-h)²/a² + (y-k)²/b² = 1
a>b

6
New cards

ellipse solve for c

c²=a²-b²

7
New cards

e=????

c/a

8
New cards

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

9
New cards

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

10
New cards

hyperbola solve for c

c² = a²+b²

11
New cards

angle of rotation of conics

cot(2 theta) = (A-C)/B

12
New cards

rotation of conics x=???

x= x’cos(theta) - y’sin(theta

13
New cards

rotation of conics y=???

y= y’cos(theta) + x’sin(theta)

14
New cards

tan = ???

sin/cos aka y/x

15
New cards

eliminate parameter =???

remove t by substitution

16
New cards

rectangular to polar: (x,y) =???

(rcos(theta),rsin(theta))

17
New cards

polar to rectangular: (r, theta) =???

(sqrt(x²+y²), tan^-1(y/x)) look for domain issues

18
New cards

sin+cos graph is???

Graphs of Sine, Cosine and Tangent

oui know this stuff or fail

19
New cards

trig table

u should know this if not study it and know it or fail

20
New cards

famous curves(polar stuffs)

knowt flashcard image

yeah know this

21
New cards

symettry tests for polar curves

knowt flashcard image

22
New cards

partial fraction denominators are???

knowt flashcard image

this is literally ch 7 dont fail on this

23
New cards

matric multiplication

only when inner dimenions ==

24
New cards

determinant of 2Ă—2 matrix formula???

knowt flashcard image

25
New cards

cramers rule???
