Homework Help: Integrate v/(v^2 + 4)

    I know that if it were 1/(v2+4) then it would be ln(v2+4) but the other v in the numberator is throwing me off, any help would be much appreciated!

    No, it wouldn't. Can you see why?

    There is no such thing as a "numberator". The proper terms for the parts of a fraction are "numerator" and "denominator". You should have learned this long before starting calculus.

    No, that is incorrect. You can verify what I said by differentiating ln(v2 + 4), which does not result in 1/(v2 + 4).
