PLEASE SHOW HOW TO DO PART B IN MATLAB. SHOW THE CODE!

3. Consider the function 1- cos f(x) sin Notice that, for small , the numerator consists of a subtraction of two numbers close to each other in size, and the denominator is also a small number (a) Find the solution for-0.001 to six significant digits. Be sure to chop. your result to 6 digits at each calculation step. (b) Use MATLAB (format long) to calculate f(0.001). Consider this to be the true value Find the true relative error between cases (a) and (b) 1+cosr (c) Multiply (x) lyr Lisyes, c al al be : nr" L** ::?m)(lily yvwanrv.xjww a n DR1.
