Answer 2

When one or both limits are infinity, it is of type 1

Answer 3

when the function has discontinuity at either of the end points, it is of type 2 improper integral

Answer 4

1st problem . 1/(x-7) has discontinuity at x=7

Answer 5

and it is the lower limit of integration

Answer 6

so can you answer the 1st question now?

Answer 7

Yea B

Answer 8

correct

Answer 9

i guess you can answer all the 4

Answer 10

What about #4?

Answer 11

cot 0 in undefined

Answer 12

infinite discontinuity. so??

Answer 13

Oh B.
But uh how is cot 0 undefined? D:

Answer 14

cot 0= cos 0 / sin 0 sin 0=0 , so denominator is 0

Answer 15

actually to compute the integral compute

Answer 16

by changing the 0 to epsilon and then after evaluating the integral, put epsilon=0
