Given
[tex]\lim _{n\rightarrow\infty}(3+i\frac{5}{n})^2\frac{5}{n}[/tex]
Solve for b.
In the given statement
[tex]\begin{gathered} \lim _{n\rightarrow\infty}(a+i\Delta x)^2\Delta x\text{ is similar in the form }\lim _{n\rightarrow\infty}(3+i\frac{5}{n})^2\frac{5}{n} \\ \\ \text{which means that } \\ b-a=5 \\ \text{since }a=3,\text{ then} \\ b-3=5 \\ b=5+3 \\ b=8 \\ \\ \text{The upper limit of the integral is }8 \end{gathered}[/tex]
The given also is a squared function, and removing a from the equation, then the integral form is
[tex]\int ^8_3(x^2)dx[/tex]
