# Thread: Definite Integral problem

1. ## Definite Integral problem

I've tried 2 answers already, but they were both wrong. Could anyone help me please? I would highly appreciate it

Your partition points are $x_0=7,~x_1=7.25,~x-2=7.5,~x_3=7.75,~x_4=8$ where $\delta x=0.25$

$LHS=\displaystyle\left( {\sum\limits_{k = 0}^3 {f({x_k})} } \right)\left( {0.25} \right)$

$RHS=\displaystyle\left( {\sum\limits_{k = 1}^4 {f({x_k})} } \right)\left( {0.25} \right)$

You do the hard work.
