Estimate $\int _ { 1 } ^ { 3 } \frac { 1 } { x ^ { 2 } } d x$

question 172

Short Answer

Estimate $\int _ { 1 } ^ { 3 } \frac { 1 } { x ^ { 2 } } d x$ using the Midpoint Rule with n = 4. Then use the error bound $\left| E _ { M } \right| \leq \frac { k ( b - a ) ^ { 3 } } { 24 n ^ { 2 } }$ to estimate the accuracy.
