Inverse
You can use
L1
(inverse, œ) with real and complex numbers, expressions, lists, and matrices. The
multiplicative inverse is equivalent to the reciprocal, 1à
x.
value
-1
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.
