I am trying to plot: Ln[x^26]Ln[x] over x, 5 to 5. I know the function is not defined for x<SQRT[6](square root of 6). When specifying the PLOT range as [5,5] I expect Mathematica not to chart anything below x<SQRT[6], but it does. My sintax is:
Plot[{Log[x^2  6]  Log[x]}, {x, 5, 5}]. I guess there should be some way to tell Mathematica to only plot the real part of a chart, to exclude any imaginary portion. Does such parameter exist, and what is it? Obviously, I could do it manually by restricting the range, but I am using mathematica as a discovery tool to confirm what I do manually.
thanks
