The value of arccos(x) can be approximated using the following equation (2n)! arccos(z)=- 04 (n!) (2n +1) 00 2+1 2 a) Write MATLAB function that uses the equation above to find the value of arccos(x) with a number of decimal places that is equal to R (for example if R=4 the result error should be less than 0.0001). b) Write MATLAB script that uses the function you created to plot the value of R in the x axis and the approximated value arccos(z) in the y axis. Use R value that ranges from 2 to 12, put a proper labels for both x, y axis, show the grid and use red dotted line with circle marker in the plot. Solution:
