Mathematica calculates exactly and therefore does not simplify unless there is an exact simplification. For an approximate number answer use the N function. In[1]:= Log[2] Out[1]= Log[2] In[2]:= N[Log[2]] Out[2]= 0.693147 David Park djmp at earthlink.net http://home.earthlink.net/~djmp/ From: Bill Ginsberg [mailto:eqmc2 at aol.com] To: mathgroup at smc.vnet.net I have Mathematica 5.0.1. When I attempt to get the Log of a number "a" by entering Log[a], it does not return the value but echoes back: Log[a]. How is this fixed?
