Question

In lectures we have an antiderivative of ln(x) is xln(x) - x. Here we like a formula for the antiderivative

Fn(x) = (ln(x))ndx

where n is a positive whole number.

In lectures we have an antiderivative of In(x) is x ln(x) – x. Here we like a formula for
the antiderivative
F„(x) = | (In(a))"dæ
where n is a positive whole number.

have the relationship
F3(x) = x(ln(x))³ – 3F2(x),
and using (c), show that an antiderivative of (In(x))³ is
F3(x) = x((In(x))³ – 3(In(x))² + 6 ln(x) – 6).
(e) Use the same idea as in (d), show that an antiderivative of (In(x))4 is
F4(x) = x((In(x))4 – 4(ln(x))³ + 12(ln(x))² – 24 1n(x) + 24)
