The integral is not defined because does not tend to 0 fast enough. The integrand must tend to 0 fast enough. Having the integrand tend to zero at the limits is not sufficient for the integral to be able to be evaluated. This is true for the improper integral tends to zero faster than any power of tends to infinity, so we may write The problem in the previous two examples is that the Fundamental Theorem of Calculus is not wrong because it does not apply to those situations. If the integral converges determine its value. The improper integral R b a f(x)dxis called convergent if the corresponding limit exists and Divergent if the limit does not exist. Improper integrands can often be evaluated because the integrand tends to 0 at the troublesome limit, or if the integrand is of the form at one or both limits, one factor tends to 0 faster than the other tends to infinity. Section 1-8 : Improper Integrals Determine if each of the following integrals converge or diverge. The second includes the factors and which tend to and 0 respectively as tends to The third includes the terms and which tend to 0 and as tends to 0.

The first of these integrands, includes the factor which tends to as tends to and which tends to 0 as tends to infinity. The integrand (the function being integrated) includes a term evaluated at one or both limits which takes the formĪnd are all improper integrals. One of the integrals is or or the limits are and An improper integral is one where either of the following holds
