Question

Can anyone create a matlab function for solving the following in the image? My professor wants for us to solve by creating functions to just change variables instead of doing it by hand. A script works just as well, thanks!! :)

This problem is Chapra 4.9 in the Applied Numerical Methods with Matlab 3rd Ed

functiono Do you expect to have difficulties evaluating this at x = 0.577? chopping. 4.9 (a) Evaluate the polynomial Compute the mation. Disc it using 3-and 4-digit arithmetic with 4.16 U of O(h) and estimate the Prob. 4.13. E turn b y=x3-7x2 +8x-0.35 0.25. enty the percent relative error. (b) Repeat (a) but express y as derivative. I der term of t 4.17 Usea estimate the Prob. 4.13. of 0.2 value of the grosi nder y = ((x-7)x + 8)x-0.35 Evaluate the error and compare with part (a). 4.10 The following infinite series can be used to approxi- mate e
