For this first assignment we're going to work with POSIX threads in order to do some mathematical calculating. First, for my benefit as well as yours, let's define the natural log of a number?: ln (x) 1)3 / 3 (x (x (x - 1) 4 / 4 1) (x 1) 5 / 5 1) 2 / 2 + (x (x 1) 6 / 6+ + If the value of x is in the interval (0,2) (in other words 0
