1. The problem statement, all variables and given/known data ∫e2xarctan(ex)dx 2. Relevant equations From the table of integrals: #92 ∫utan-1udu = (u2+1)/2)tan-1-u/2 + c or #95 ∫untan-1udu = 1/(n+1)[un+1tan-1-∫ (un+1du)/(1+u2) , n≠-1 3. The attempt at a solution The answer is 1/2(e2x+1)arctan(ex) - (1/2)ex + C I don't know if I'm supposed to make a substitution first and if so what I should substitute and/or if which from I should use from the table. I've tried to make the initial substitution of e2x and ex and they both got me seemingly nowhere. Help please.
