Approximate your solution $to$ FOUR decimal places

$(ROUNDING)$

Use Trapezoidal Rule $to$ approximate ${\displaystyle \underset{1}{\overset{2}{}}}xlogxdx$

using $n=4.$

Answer: ${\displaystyle \underset{1}{\overset{2}{}}}xlogxdx$~~

Find $an$ upper bound for the error $in$ your

approximation.

HINT: Write your answer $as$: mantissa ${10}^n.$

Answer: mantissa $=$
