360 divided by n Where n is the number of sides

12 of 62

Arc Length

θ divided by 360 x π x d Where d is the diameter

13 of 62

Area & Circumference of a circle

C=π x d A=π x r^2 Where r is the radius

14 of 62

1/2 x a x b x Sin C

17 of 62

Bearings

1. Join the two places 2. Draw a north line on the asked place 3. Measure the angle 90 Degrees from north 4. All bearings should have 3 figures

18 of 62

Circle Theorems 1-7

I'm literally the worst at this lmao. It also doesnt help with this website not letting you use pictures so now it's going to be very hard to describe them all ahaha; good luck figuring it out!

19 of 62

Triangle at diameter touching circumferance

The angle in a semi-circle is 90 Degrees

20 of 62

Arrowhead

The angle at the centre is twice the angle at the circumference

21 of 62

Bow Tie

The angles in the same segment are equal

22 of 62

Quadrilateral

Opposite angles in a cyclic quadrilateral sum to 180 Degrees

23 of 62

radius & a tangent

The angle between a radius and a tangent is 90 Degrees

24 of 62

triangle & a tangent

Alternate Segment Theorem

25 of 62

two tangents

Tangents which meet at the same point are equal in the lengthy

26 of 62

Iteration

X^n+1= 3/5 - Xn^3 divided by 5

27 of 62

Congruent Triangles *name all 4*

SSS=Side Side Side ASA=Angle Side Angle SAS=Side Angle Side RHS=Right-Angle Hypotenuse Side

28 of 62

Equation of a circle

x^2+y^2=r^2

29 of 62

Graphs of Exponential Functions (terrible explanation but err just memorize the equation lmao)

y=2^x Should look like a descending curve and should remain in positive y

30 of 62

Graphs of Reciprocal Functions (also a terrible explanation but again just memorize the equation)

y=1/x Should look like two curves: one in positive xy and one in negative xy

31 of 62

Cubic Graphs

y=x^3 - 3x - 1 Basically looks like two curves connected at the y axis *lmao like a worm*

32 of 62

Transformation of Graphs 1-4

lol lets see how well i do on describing these graphs now

33 of 62

Y=-f(x)

a reflection of y=f(x) in the x-axis

34 of 62

y=f(-x)

a reflection of y=f(x) in the y-axis

35 of 62

y=f(x)+a or y=f(x)-a

+a moves y=f(x) a squares up or -a moves y=f(x) a squares down

36 of 62

y=f(x+a) or y=f(x-a)

+a moves y=f(x) a squares to the left or -a moves y=f(x) a squares to the right

37 of 62

Graphs of Trigonometric Functions 1-3

These coordinates are good to know like if you're doing a non-calc or actually.. with a calc as well because my calculator is actually ******

38 of 62

y=sin x

*S Shape* (0,0) (90,1) (180,0) (270,-1) (360,0)

39 of 62

y=cos x

*U Shape* (0,1) (90,0) (180,-1) (270,0) (360,1)

40 of 62

y=tan x *This one is so ******* confusing*

*3 curves* (0,0) to (90,1) (90,-1) to (180,0) (180,0) to (270,1) (270,-1) to (360,0)

41 of 62

Equation for Frequency Density (histograms)

Frequency divided by Class Width For example if the class width was 15<l≤25 the class width would be 10

42 of 62

Equation for Frequency (histograms)

Frequency Density x Class Width

43 of 62

nth term for Quadratic Sequences

nth term=an^2+bn+c Sequence=a+b+c First differences=3a+b Second differences=2a

44 of 62

Percentage Change

Change divided by Original x 100

45 of 62
