Consider the following implementation of an iterative method: from numpy import cos, sin, log. x = 0.5 err = abs (cos(x)+log(x)) while err > 1e-6: dx = (cos(x)+log(x))/(-sin(x) +1/x) x += - dx err = abs(dx) print (x) a) What method is supposed to be implemented above? b) Write down the specific equation being (iteratively) solved by the algorithm. c) An error is present in the code, spot it.
