### Line Graphs

Line graphs
Line graphs show how information is linked together,  if the line goes diagionally up to the right then there is a positive correlation and if it goes to diagonally up to the left there is a negative correlation.

## Photos

The gradients of these lines are 2 & -1/2.

# Histograms

## Rich sticky notes

### What is a histogram?

A histogram is way of displaying data. It looks like a bar chart but it is completely different and much harder to plot.

Points to remember ~

-Area of the bar instead of the height it reaches

-Uneven class widths

FORMULA

Frequency Density = Frequency รท Class Width

# Area of a triangle

## Rich sticky notes

1/2 ab sin C

### How to work it out?

a = 5.2

b = 7.1

c = 42

Type into the calculator ' 1/2 x 5.2 x 7.1 x sin(42)

# Volume Scale Factor

## Rich sticky notes

sin=opposite / hypotenuse

# SOH CAH TOA

### SOH CAH TOA

SOH ~ Sin, Oppostie / Adjacent

CAH ~ Cos, Adjacent / Hypoteneuse

TOA ~ Tan, Opposite / Adjacent
