what's the antiderivative of

[afcwestwarrior]

2/2x+1

how do i figure this out

[afcwestwarrior]

is it 1/2 (2x+1)

[Feldoh]

Solve it by u-substitution where u=2x+1

[Astronuc]

2/2x+1

how do i figure this out Is that \frac{2}{2x+1}?

Then along the lines of Feldoh's comment, what is the antiderivative or integral of 1/u

or \int\frac{du}{u}
