    12 The final polynomial was such that ''E'' was approximately 0.000546277. More particularly, ''|exp(-1) - P(-1)|'' =  0.000546277 and  ''|exp(1) - P(1)|'' =  0.000546277.

    14 The error values in -1 and 1 are the same but the '''relative error''' values are not: it is about 0.15% for -1 whereas it is about 0.02% for 1.
     12A look at the error graph indicates that the error values in -1 and 1 are the same but the '''relative error''' values are not: it is about 0.15% for -1 whereas it is about 0.02% for 1.
