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:
‚Г2.45`
„В\2.3`
In RPN mode, the argument is entered before the function
2.45 ‚Г
2.3\ „В
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 V 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
