I have a follow-up to this. Although I get a partial graph, I get a message about some domain values that return non-real machine size numbers, or something to that effect. In fact, I defined f[x_]=(Sin[x])^(1/3) and when I found f[values in error message] mathematica returned one of the imaginary solutions, as opposed to the real solution. I understand that I can 'force' mathematica to return the real solution, but shouldn't it do that by default? -----Original Message----- From: Tim 9-23 [mailto:bendoftimeb at stny.rr.com] To: mathgroup at smc.vnet.net Subject: [mg29977] [mg29947] notation help: f(x) = (sin x)^(1/3) How do I plot this. I must not be entering it correctly. It's the plot of the cube root of the Sine function. Plot[[Sin[x]]^(1/3), {x, -10, 10}] isn't working. Thanks. My email address is anti-spammed.
