Question 4 (Drag and drop the missing words) An is the of a definite integral as an endpoint of the interval of integration approaches either a specified real Not yet answered number or positive or negative Although the integral Marked out of 9 da P Flag question the integral dr is improper. In this case, we define the improper integral as a limit dr lim In general, an improper integral if the limit defining it Thus for example d. does not It is possible for an improper integral to to infinity. For instance, dz = lim However, there are many improper integrals which diverge in no particular direction, such as z sin zdr limit diverge exists Riemann integral converge infinity divergent improper integral not improper infinite integral definite integral oscillates converges zero
