Answer:
upper bound for the error, | Error | ≤ 0.0032
Step-by-step explanation:
Given the data in the question;
< e < 3
Using Taylor's Error bound formula
| Error | ≤ ( m / ( N + 1 )! )
where m =
so we have
| Error | ≤ ( 3 / ( 3 + 1 )! ) -0.4 ⁴
| Error | ≤ ( 3 / 4! ) -0.4 ⁴
| Error | ≤ ( 3 / 24 ) -0.4 ⁴
| Error | ≤ ( 0.125 ) -0.0256
| Error | ≤ ( 0.125 ) 0.0256
| Error | ≤ 0.0032
Therefore, upper bound for the error, | Error | ≤ 0.0032
