5. (1 pt each) This question is about approximate integration. M17 a) Use the Trapezoidal rule with P1! = 4 to approximate the value of I sin(x2)dx. b) Find an upper bound on the error involved in the approximation you obtained in (a). Note: for this question you do not need to nd the best possible 191'si1'npl'5,r use 45 as the K value. 6. (2pts each) Determine whether each of the following integrals is convergent or divergent. Evaluate the integral if it is convergent (give an exact answer). to b) J. sin(x) cos (x]+2dr 6) 4 _15 are air "|8 =l
