WAEC/NECO MATHEMATICS/PHYSICS SYMBOLS

Below are the Maths Symbols you will see in Our Solutions Tomorrow,

So u need to study them very well.

/ means DIVISION
* means multiplication
tita u should know dat.
rais means raise to power
^ means raise to power
sqr rut/ squar rut means square
root
—-(1) means equation 1
yr means year
f(x-xbar) means x MINUS x BAR as
in statistics which means that

MINUS WILL BE ON TOP OF x.
, (Comma) means NEXT LINE, THIS
MEANS THAT THE FOLLOWING
NUMBER IS UNDER THE NUMBER IT
IS FOLLOWING i.e UNDER. It is
usually used during STATISTICS
when drawing a table.

EXAMPLE 1.
X:1,2,3,4,5,6
FX: 4,6,8,10,12
FX-Xbar: 10,8,6,4,2,1

DRAW A TABLE WITH X|FX|(FX-
Xbar)
The above statement means
that:
~For X, it has 1 2 3 4 5 6 under it.
which means 1 is under 2, 2 is
under 1, 3 is under 2, 4 is under 3
and so on…
~Under FX you have 4, then 6
under 4, then 8 under 6, then 10
under 8, then 12 under 10…..
~Under FX-Xbar you have 10,
then 8 under 10, then 6 under 8,
then 4 under 6, then 2 under 4,
then 1 under 2….

ANOTHER EXAMPLE:
Class interval:
60-64,65-69,70-74,75-79,80-84,85-89,90-94,95-99.
X: 62,67,72,77,82,87,92,97.
F: 2,3,6,11,8,7,2,1.
FX:
124,201,432,847,656,609,184,97.
F(x-x bar)2:
561.12,414.18,273.36,33.66,84.48,476.42,351.12,333.06

MEANING OF THE ABOVE
EXPRESSION:
Bar means Minus on top of d
number or Variable and comma
means next line which means
each of them are unda. Eg 60-64
is unda Class interval, then 65-69
is unda 60-64,etc .So comma
means unda.

NOTE THAT WHEN U SEE
SOMETHING LIKE THE ABOVE TWO
EXAMPLES, U WILL NEED TO DRAW
A TABLE..
I WILL UPDATE MORE LATER.
