log(, 10^(, ln(
You can use
log(
(logarithm,
«
),
10^(
(power of 10,
y G
), and
ln(
(natural log,
μ
) with real
or complex numbers, expressions, and lists.
Exponential
e^(
(exponential,
y
J
) returns the constant
e
raised to a power. You can use
e^(
with real or
complex numbers, expressions, and lists.
Constant
e
(constant,
y
[e]
) is stored as a constant on the TI-84 Plus. Press
y
[e]
to copy
e
to the cursor
location. In calculations, the TI-84 Plus uses 2.718281828459 for
e
.
Negation
M
(negation,
Ì
) returns the negative of
value
. You can use
M
with real or complex numbers,
expressions, lists, and matrices.
