Hi, got a question about the intergral of e^x+1/e^x-1
I put u=e^x-1, dx=du/e^x
And i am left with the intergral of 1/u+1, which isnt right. Can anyone help me?
Yes, I think that was a typo/slip. Just in case a picture helps - in confirming your reasoning re the typo but then also getting past your alleged 1/(u+1)...
... where (key in spoiler) ...
