enter the function XROOT followed by the arguments (y,x), separated

by commas, e.g.,

‚»3‚í 27`

In RPN mode, enter the argument y, first, then, x, and finally the

function call, e.g.,

27`3‚»

•

Logarithms of base 10 are calculated by the keystroke combination

‚Ã

(function LOG) while its inverse function (ALOG, or

antilogarithm) is calculated by using

„Â

. In ALG mode, the

function is entered before the argument:

‚Ã2.45`

„Â\2.3`

In RPN mode, the argument is entered before the function

2.45 ‚Ã

2.3\ „Â

Using powers of 10 in entering data

Powers of ten, i.e., numbers of the form -4.5×10

-2

, etc., are entered by using

the

key. For example, in ALG mode:

\4.5V\2`

Or, in RPN mode:

4.5\V2\`

• Natural logarithms are calculated by using ‚¹ (function LN)

while the exponential function (EXP) is calculated by using „¸.

In ALG mode, the function is entered before the argument:

‚¹2.45`

„¸\2.3`

In RPN mode, the argument is entered before the function

1 2 ... 52 53 54 55 56 57 58 59 60 61 62 ... 174 175
