Approximate $\int _ { 1 } ^ { 5 } \frac { 1 } { 2 x ^ { 2 } } d x$

Short Answer

Approximate $\int _ { 1 } ^ { 5 } \frac { 1 } { 2 x ^ { 2 } } d x$ ; n = 8, by (a) the trapezoidal rule, (b) the midpoint rule, and (c) then find the exact value of the integral.
Enter just a, b, c as real numbers all rounded to two decimal places. Do not label, but answer in the above order using commas to separate.
