f(x)- (x^2-5x)/x^3
Let us
simplify.
==> f(x)= x^2/x^3 -
5x/x^3
==> f(x)= 1/x
-5/x^2
==> f(x)= 1/x -
5x^-2
==> Now we will find the
integral.
==> Int f(x)= Int 1/x - 5x^-2
dx
==> Int f(x) = ln x - 5x^-1/-1 +
C
==> Int f(x) = lnx +
5/x
Now we will find Int
f(2)
==> F(2) = ln2 + 5/2 = 2.5 + ln
2
==> F(1) = ln1 + 5 =
5
Then the bounded area is F(2) -F(1) = 2.5 +ln2 - 5 =
-1.81
==> Then the area is 1.81 square
units.
