I am interested in the use of Sage as a teaching tool at all grade levels. At the moment, I'm trying to weave Sage into an introductory algebra curriculum.
I can graph all the basic functions with plot(x), replacing x with x^2, x^3, 1/x, etc. The one I can't get to work is x^(1/3). I've tried to express the cube root function several different ways. The expression I'm using now is: sage: show(plot(x^(1/3),-10,10),figsize=[5,5],xmin=-10,xmax=10,ymin=-10,ymax=10) I receive the error message "TypeError: 'float' object is unsubscriptable" Also, is the expression above the most succinct way to generate a graph with this kind of view, x and y ranging -10 to 10? Thanks for any advice.
