SUMMARY
The integral ∫^{2∏}_{0}\frac{cosθ}{13+12cosθ} can be evaluated using the Cauchy Residue Theorem, yielding a result of -\frac{4∏}{15}. The discussion highlights a common error in the factorization of the polynomial 6z^3+13z^2+6z, which should be correctly expressed as 6z(z+2/3)(z+3/2). The application of the substitution method is also emphasized as crucial for solving the integral accurately.
