Explain how to evaluate \(\int_{a}^{\infty} f(x) d x\).
Problem 2E
Explain how to evaluate .
Answer;
Step 1;
The given integral is f(x)dx.
Now , we have to evaluate f(x)dx.
We , know the formula dx =
+C , C is constant ………..(1)
Therefore , dx =
+C , since from (1).
= +C.
= (
-
) +C
= (
-
+C , since as x =
, then f(
) =
.
= (
) +C , since
+p =
-p =
= C(
) .
= .
