please solve this and explain how the code will works

Question: Write a MA B function that calculates the approximate value of arctan(x) using the Maclaurin series approximation: arctan(x) = x +... The function should accept 3 parameters: value of x, number of significant figures accuracy i.e. n, and the maximum number of iterations. In the function, use Es = (0.5 x 102-) % in order to continue until the ea falls below this criteria. The function should return 3 values: the approximate value of arctan(x) at the end of the program, final Eq and the number of iterations it took Submit the snapshots showing the program running from the command prompt for x-0.4 and 0.8
