What are the 4 transformations?
- translation
- reflection
- rotation
- enlargement
How do you find the roots?
Factorise (into two brackets)
How do you find turning point?
Complete the square
With vectors, what do the two values mean?
One on top is x (left/right)
One on bottom is y (up/down)
With transformations, when ‘a’ is inside the brackets which axis is involved?
X-axis
With transformations, when ‘a’ is outside the brackets which axis is involved?
Y-axis
y = f(x+a)
Translation (-a, 0)
along x-axis
y = f(x) + a
Translation (0, a)
along y-axis
y = a f(x)
Enlargement on/in y-axis
scale factor of a
y = f(ax)
Enlargement in x-axis
scale factor of 1/a
y = f(-x)
Reflection in y-axis
y = -f(x)
Reflection in x-axis
What are the three rules with bearings?
- Start from North
- Go clockwise
- Use 3 digits
What does the word FROM tell us?
Where we start
What do bearings tell us?
Direction of travel
