Matrices
Example
Alt Text
1 2
A = (3 −4)
4 5
A is the 3 by 2 matrix
whose first row is 1,
[pause] 2, whose second
row is 3, [pause] -4 and
whose third row is 4,
[pause] 5.
y = |𝑓(𝑥)|
y equals the modulus of, f
of x
y = |𝑎 + 𝑏|
y equals the modulus of, a
+b
g-1(a)
g inverse of a

Notes
3 by 2 means 3 rows by
2 columns – always
give rows first
pause before a + b
Lower case f of x equals
2x over 9 when zero is less
than or equal to x, is less
than or equal to 1.
Lower case f of x is equal
to 2 over 9 when 1 is less
than x, is less than 4.
Lower case f of x is equal
to 2 over 3 minus x over 9
when 4 is less than or
equal to x, is less than or
equal to 6.
In PURE MATHS
units this can be
pronounced as f of x
but in STATISTICS
the case (lower case f
of x, or upper case F
of x) should be
specified since the
two can represent two
distinct but related
functions.
left parenthesis, 8 x cubed
+ 4, right parenthesis d x
say d x with a very
slight separation
between and use
parentheses
