    B Area under the curve of a Polar Graph

    I disagree with your disagreement. Since the integral must be evaluated at both points in order to obtain the required solution, the equation must be continuous and defined on the given interval to be differentiable. My stance would be that the lower bound would need to be the 'limit as x...
