Using Mat Lab 2. Consider Finish writing the function myAtan () that returns (in outarg) an approximation of the arctangent of an input x, using the Taylor Series expansion shown below. Use a while loop that ends when the magnitude of each successive term becomes less than 0.001. function [outarg] = myAtan (x) % MYATAN estimates the arctangent of x arctan(x) = 20 (-1)k x2k+1 2k+1 k=0
