Given the integrand , before evaluating the integral function, we will need to simplify the function first by applying long division as shown in the attachment.
Hence the partial form of the function
Integrating its partial sum
<em>NB: Find the partial sum calculation also in the attachment. </em>
Probably a for plot, because It shows how close each value is, or if the values are all scattered around. it gives you a more accurate ways of seeing how close the data is. hope this helped
