Version 4.0.1 Windows 98 first edition Does not correctly graph y = X^(3/5) - does not display the interval (-inf, 0) Thanks-- Marvin Hernandez ___________________________________________________________ Sent by ePrompter, the premier email notification software.

Marvin, Thanks for the notice. While x^(3/5) does indeed have a domain that includes negative numbers, neither GraphCalc, nor any other graphing calculator I know, graphs this region. This is due to the fact that (3/5) is evaluated first and transformed into a decimal that is very very close 0.6 (but not exactly). And while x^0.6 does exist, x^(very very close to 0.6) does not. -Mike On May 03 21:08, Marvin D.

Marvin, Actually, both of the work around equations you gave me work on GraphCalc v4.01. I entered: x^3^(1/5) x^(1/5)^3 x^3^0.2 The weird thing is that: x^0.6 does not work for me. Anyway, thanks for the workarounds, I hope you get them to work. -Mike Arrison GraphCalc On May 04 10:35, Marvin D.
