To calculate the area, we'll have to evaluate the improper
integral of the function f(x) = 1/(x^0.6) = 1/x^(6/10) =
1/x^(3/5)
y
`oo`
`int`
dx/x^(3/5) = lim `int` dx/x^(3/5)
1
y->`oo` 1
We'll evaluate the definte integral using
Leibniz Newton
formula:
y
`int` dx/x^(3/5) =
F(y) - F(1)
1
We'll calculate
the indefinite integral of the function:
`int` x^(-3/5)dx =
x^(-3/5 + 1)/(-3/5 + 1) + c
`int` x^(-3/5)dx = 5x^(2/5)/2 +
c
F(y) - F(1) = 5y^(2/5)/2 -
5/2
Now, we'll evaluate the
limit:
lim [F(y) - F(1)] = lim F(y) - lim
F(1)
y->`oo` y->`oo`
y->`oo`
lim [F(y) - F(1)] = `oo` -
5/2
y->`oo`
lim [F(y) -
F(1)] =
`oo`
y->`oo`
Since
the limit is infinite, the integral is divergent and the area is not
finite.
