Let f(x)=-x+Sin(Pix) and p0 = 0.9. Use Newton's method to find p2 (hand calculation). Could pO- ArcCos[1/i 0.396 be used for this problem (why, why not)? Plot the function graph on interval[-1, 1]. Write down the steps and solve the same problem using the root finding codes in MATLAB. Note: In Matlab environment the trigonometric functions are evaluated in radians Try: >>help cos cos Cosine of argument in radians. cos(X) is the cosine of the elements of X
