Exponential Exponential Exponential 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.
e^( power )
Constant Constant Constant 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 Negation Negation Negation
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
