# x26 dxby using the formal definition of the definite integral:In this problem you will calculateC.ebf(x) dx limn-x(a) The interval [0, 2] is divided into N equal subintervals of length Ax. What is Ax (in terms of n)?Ax = 2/n(b) The right-hand endpoint of the kth subinterval is denoted X. What is x(in tems of k and n?2k/n(c) Using these choices for Xand Ax, the definition tells us thatx2 6 dxlimn ooLi-1.f(x)Ax (in terms of k and n)?f(x)Ax = "(2k/n)^2)+6)*(2In)(d) Express(x;)Ax in closed forrm.
