Math help required - simple intergration

what is the intergral of (0.5) / (x + 1) ??
i understand it would be .5 ln (x + 1).

alternatively.... isnt (.5) / (x+ 1) the same as 1 / (2x + 2)???? correct me if i am wrong, but isnt the intergral of this now 0.5 ln (2x + 2)
what am i doing wrong?? thanks alot

The integral of .5/(x+1) is .5 ln (x+1) + C
