In Problems 1 through 8, compute the successive approximation formula to compute y n ( x ) for n ≤ _ 4 . Then write the exponential series for which these approximations are partial (perhaps with rile first term or two missing; for example, e x − 1 = x + 1 2 x 2 + 1 6 x 3 + 1 24 x 4 + ... ).

d y d x = y , y ( 0 ) = 3
