Q.7 A 2nd degree polynomial, f(x) has values of 1,4 and 15 at x = 0, 1 and 2, respectively. The integral 348 2 [f(x)dx is to be estimated by applying the 0 trapezoidal rule to this data. What is the error (defined as "true value - approximate value) in the estimate? Q.7 A 2nd degree polynomial, f(x) has values of 1,4 and 15 at x = 0, 1 and 2, respectively.
