– [Func Analysis] > [Summation(Σ)]
1 (,)1 (,)5
Logarithm(logab), Logarithm(log)
Use
(log) or – [Func Analysis] > [Logarithm(log)] to input
log
a
b
as
log (a, b). Base 10 is the initial default setting if you do not input anything
for a.
Example 1: log
10
1000 = log 1000 = 3
(log)1000
Example 2: log
2
16 = 4
(log)2 (,)16
The key (or – [Func Analysis] > [Logarithm(logab)]) also can be
used for input, but only while MathI/MathO or MathI/DecimalO is selected
for Input/Output on the SETTINGS menu. In this case, you must input a
value for the base.
Example 3: log
2
16 = 4
2 16
Natural Logarithm
Use
(ln) or – [Func Analysis] > [Natural Logarithm] to input "ln".
Example: ln 90 (= log
e
90) = 4.49980967
(ln)90
Probability
This section explains commands and functions that you can input after
performing the operation:
– [Probability].
