Question #1 (Easy): Improper Integrals With Infinite Interval
There are two types of improper integrals: Type 1 is integrals with infinite interval, such as
Type 2 is integrals whose interval is not infinite but fixed at , but has point(s) of discontinuity
within the interval, such as vertical asymptotes.
Explain why the given integral is improper.
The integral shows that the interval is . Since the interval is infinite, the integral is an improper
integral of Type 1.
