Chapter 1 Terms: Basic Math and Stats Review Flashcards
anything to which a number can be attached
quantity
a number only
pure quantity
contains a number and a unit
physical quantity
magnitude but no direction such as speed and energy
scalar
has a magnitude and direction (e.g velocity and momentum)
vector
y= f(x)
function; “y is function of x”
x= f^-1 (y) = f^-1 [f(x)]
inverse function; “x is an inverse function of f(x)”
=
is defined as
lxl
absolute value; magnitude of x
dx
differential (a small change in x)
n!
factorial value
e
base of the natural
(x^n)(x^m)=
x^n+m
(x^n)/(x^m) =
x^n-m
x^0 =
1
(x^n)^m =
x^(n)(m)
x^-n =
1/x^2
an expression of a very small or very large numbers as powers of ten
scientific notation
the precision of measured or calculated physical quantity
significant figures
a special function that can be expressed as natural (logan) and common (log10n)
logarithms
logam + logan
logamn
logam- logan
loga (m/n)
loga^mn
n logam
loga1 =
0
differentiation
the slope of a curve in calculus
integration
the area under the curve in calculus; includes measurements of height and width
