Question

Evaluate the indefinite integral of:
x^4tanx dx

I would like a hint please.

Answer 1

Is the tan(x) a part of the exponent?

Answer 2

No

Answer 3

It is (x^4)(tanx) dx

Answer 4

I think the indefinite integral can only be expressed as an infinite series.

Answer 5

Is this a homework question or something?

Answer 6

yes

Answer 7

Interesting. I feel that I've seen this question before, but my instinct now tells me that it can only be evaluated as a series. Let's see...

y=(x^4)tan(x), ln(y)/ln(x)=4+ln(tan(x))... No, this approach doesn't work...
