FindRoot with Logarithmic terms
Posted:

Hi, I'm trying to find the roots of a logarithmic equation that I've plotted successfully (I can see both roots are between 0 and 1).
expr = 7500*x*(1  x) + 325*8.314*(x*Log[x] + (1  x)*Log[(1  x)]) FindRoot[expr == 0, {x, 0, 1}]
FindRoot:nlnum: the function value(indeterminate) is not a list of numbers with dimensions {1} at {x} = {0.}
any ideas?
thanks
