So in this case I am actually taking the cube root of a negative number-not taking the cube root of a positive number and then negating it.(03-30-2015 06:15 PM)John Colvin Wrote: This inconsistency also occurs in RPN mode. It might be something to do with raising the number to the 1/3 power vs. taking the cube root. For example if I place -8 on the stack and then 1/3 on the stack and hit the x^y key I get a complex root, but if I place -8^(1/3) on the stack I get -2 after pressing eval. |
