Transcribed Image Text:Let \( f(x) = xe^x \).
(a) Apply the composite trapezoid rule with \( m = 6 \) to approximate \(\int_0^1 f(x) \, dx\). Compute error by comparing with the correct value.
(b) Replace \( f(x) \) by its 4th order Taylor polynomial to approximate \(\int_0^1 f(x) \, dx\). Compute error by comparing with the correct value.
(c) Make a table of error of three-point centered-difference formula for \( f'(0) \) with \( h = 0.1, 0.01, 0.001 \).
