The approximate value of \(\int\limits_2^3 {\dfrac{1}{x}} \) using the trapezoidal rule and 3 function values is?

The approximate value of \(\int\limits_4^6 {{{\log }_{10}}x\,dx} \) using the trapezoidal rule and 5 function values is ?

Using the trapezoidal rule the area of the adjacent figure is?

Using the trapezoidal rule and the below table, determine the approximate distance travelled, given that \(t\) is in seconds and \(v\) is in \(m/sec\)

\[\begin{array}{ | c | c | c | c | c | c |}\hline t & 0 & 1 & 2 & 3 & 4 \\ \hline v & 1.2& 1.6& 1.2& 2.1& 1.8\\ \hline \end{array}\]
