I don't know how to start and solve this integral. Can you help me? $$\int \dfrac{dx}{1+x^{7}}$$
• Just can just write done the seven seventh roots of $-1$ explicit, e.g. using Eulers formula. – Andreas Rüdinger Jan 13 '17 at 21:03
• @SimpleArt Probably means a comment linking to Evaluate $\int\frac1{1+x^n}dx$ for $n\in\mathbb R$. (It was added automatically with a vote to close as a duplicate and it was removed after the question was closed.) – Martin Sleziak Jan 14 '17 at 10:11
