does someone know how to solve the integral from -π to π of (7+x-x^3)dx/(2-|sin7x|)?

What have you tried? We need to see your work. \(\displaystyle \displaystyle \int_{-\pi}^\pi \dfrac{(7 + x - x^3)\ dx}{2 - |\sin(7x)|}\) It looks well enough behaved .. I would do it numerically. What other methods do you know?
