G.5) Rectangles, trapezoids, midpoints and parabolas O G.6.a.i) Euler approxim ation of f[x] (order of contact ] with f[x] at x = b) Clear [feuler, f. x. b] : feuler [x_ . b_] = f[b] - (x - b) f '[b] gaincel ( -b + x] + f[b] Here is a plot f'[x] for f [x] = x Log[x] - I together with the plot of a certain rectangle: a = 2: C = 8: f [x_ ] = x Log [x] - X: rectangle = Graphics [{Darker [Yellow] .

If you take b = a, then feuler[c. b] - feuler[a, b] measures the area inside the rectangle. 0 G.6.a.ii) Does this work for other functions and other choices of a and c as well
