Question

Difficult Calculus question that I need him with, please help me!

Answer 1

Given

`\lim _(n\rightarrow\infty)(3+i(5)/(n))^2(5)/(n)`

Solve for b.

In the given statement

`\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(5)/(n))^2(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}`

The given also is a squared function, and removing a from the equation, then the integral form is

`\int ^8_3(x^2)dx`
