You can use
log(
(logarithm,
«
),
10^(
(power of 10,
y
[
10
x
]), and
ln(
(natural log,
µ
) with real or complex
numbers, expressions, and lists.
log(
value
)
10^(

ln(

)
e^(
(exponential,
y
ã
e
x
]) returns the constant
e
raised to
a power. You can use
e^(
with real or complex numbers,
expressions, and lists.
e^(
power
)
e
(constant,
y
[
e
]) is stored as a constant on the TI
-
83.
Press
y
[
e
] to copy
e
to the cursor location. In
calculations, the TI
-
83 uses 2.718281828459 for
e
.
M
(negation,
Ì
) returns the negative of
value
. You can use
M
with real or complex numbers, expressions, lists, and
matrices.
M
value
EOS rules (Chapter 1) determine when negation is
evaluated. For example,
L
A
2
returns a negative number,
because squaring is evaluated before negation. Use
parentheses to square a negated number, as in
(
L
A)
2
.
Note: On the TI
-
83, the negation symbol (
M
) is shorter and higher than
the subtraction sign (
N
), which is displayed when you press
¹
.
p
(Pi,
y
[
p
]) is stored as a constant in the TI
-
83. In
calculations, the TI
-
83 uses 3.1415926535898 for
p
.
