∫(1/(x^2-x+1)dx

Homework Equations



No idea


The Attempt at a Solution



I tried this by the subsitution method but that attempt was feeble as it only complicated the integral even further.
let t=x^2-x+1

this integral can neither be split into partial fractions.

I have no idea how to proceed forward.

Write (x^2 - x +1) as (x-1/2)^2 +3/4. Then make the substitution u=x-1/2. Now the integrand is in the form of 1/(u^2 + a^2), which hopefully you know how to do with a trigonometric substitution.
 

Thread 'Finding the nth roots of a complex number'

There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
