2016-01-31 14:07:41 -0500 | commented answer | fractional exponents error: "negative number to a fractional power not real" Thanks, Tmonteil. My problem is exaclty what you wrote in sage lines. I need to plot a potential function of the form Why sage always chooses the complex root? How do I overcome this issue? |

2016-01-30 15:55:33 -0500 | asked a question | fractional exponent not working correctly. Error: "negative number to a fractional power not real" Hi. I'm having a problem with fractional exponents and higher order roots in sage. If I put (-2) I need to plot a function like V(x) = x^[ (2n+1)/n ], where n is interger. However, sage returns the error 'negative number to a fractional power not real' and plot only the positive branch. |
