An estimated error of the multiple-application trapezoidal rule is: Ea = (b - a)³ 12n2 -f" where f" is the average value of the second derivative of the function over the entire interval and is computed using the following equation. b S₂ f" (x)dx f" b-a 2. Consider the function f(x) = 0.2 + 25x-200x² + 675x³- 900x4 + 400x5. Use the MATLAB script “Trapm_main.m" (which uses Trapm function realized in step 1), to estimate the value of the integral of the function f(x) over the interval (0, 0.8) with n = 2 segments. The value of n can be modified in the script "Trapm_main.m”. You are required to fill the following table. how to find Ea using MATLAB??? b = 0.8 n h In Et Ea a = 0 2 0.4 1.0688 34.85% ??? n = 2
