A very convenient way to accomplish this is with the RootSearch package Ted Ersek wrote that can be found at <http://library.wolfram.com/infocenter/MathSource/4482/> =46or example after loading the package In[2]:= RootSearch[6*Cos[x] - 5*Sin[x] == 0, {x, 0, 2*Pi}] Out[2]= {{x->0.876058},{x->4.01765}} -- To reply via email subtract one hundred and four
