7.8 - Improper Integration Math 142 - Spring 2020 7.8 - Improper Integration Goals of this section: Identify and evaluate improper integrals. f An improper integral is an integral that represents the (signed) area of an unbounded region. There are two ways that an integral can be improper: it has an Definition of an Improper Integral of Type 1: For a fixed number a , we define the improper integral Z 1 a f ( x ) dx using a limit: if this limit exists (as a finite number). If the limit exists, then we say the improper integral converges . Otherwise, the integral di- verges . The improper integral Z a -1 f ( x ) dx is defined as above, and Example 1: Determine whether Z 1 1 1 x dx converges or diverges, and evaluate if possible. 1 of 4 infinite integral i e or is a limit of integration on the bounds an infinite discontunity i.e is a vertical asymptote flxtdx fijno.SI faddy i a t fig Sea fix d Break into 2 To fix d f.aoofcxldxtfaofc.de cases for any number a that is conoient make a any term Evacuate J de If noo Sit DX the integral ist i In 11 i i
