You can use log( (logarithm, «), 10^( (power of 10, y
[10x]), and ln( (natural log, µ) with real or complex
numbers, expressions, and lists.
log(value) 10^(power)ln(
value)
e^( (exponential, y ãex]) 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.
Mvalue
EOS rules (Chapter 1) determine when negation is
evaluated. For example, LA2 returns a negative number,
because squaring is evaluated before negation. Use
parentheses to square a negated number, as in (LA)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.
